-C.6 Compatibility For Old Extensions
-====================================
-
-*note Dynamic Extensions::, describes the supported API and mechanisms
-for writing extensions for 'gawk'. This API was introduced in version
-4.1. However, for many years 'gawk' provided an extension mechanism
-that required knowledge of 'gawk' internals and that was not as well
-designed.
-
- In order to provide a transition period, 'gawk' version 4.1 continues
-to support the original extension mechanism. This will be true for the
-life of exactly one major release. This support will be withdrawn, and
-removed from the source code, at the next major release.
-
- Briefly, original-style extensions should be compiled by including
-the 'awk.h' header file in the extension source code. Additionally, you
-must define the identifier 'GAWK' when building (use '-DGAWK' with
-Unix-style compilers). Otherwise, the definitions in 'gawkapi.h' will
-cause conflicts with those in 'awk.h' and your extension will not
-compile.
+File: gawk.info, Node: Notes summary, Prev: Extension Design, Up: Notes
- Just as in previous versions, you load an old-style extension with
-the 'extension()' built-in function (which is not otherwise documented).
-This function in turn finds and loads the shared object file containing
-the extension and calls its 'dl_load()' C routine.
-
- Because original-style and new-style extensions use different
-initialization routines ('dl_load()' versus 'dlload()'), they may safely
-be installed in the same directory (to be found by 'AWKLIBPATH') without
-conflict.
-
- The 'gawk' development team strongly recommends that you convert any
-old extensions that you may have to use the new API described in *note
-Dynamic Extensions::.

-@node Old Extension Mechanism
-@appendixsec Compatibility For Old Extensions
-
-@ref{Dynamic Extensions}, describes the supported API and mechanisms
-for writing extensions for @command{gawk}. This API was introduced
-in @value{PVERSION} 4.1. However, for many years @command{gawk}
-provided an extension mechanism that required knowledge of @command{gawk}
-internals and that was not as well designed.
-
-In order to provide a transition period, @command{gawk} @value{PVERSION} 4.1
-continues to support the original extension mechanism.
-This will be true for the life of exactly one major release. This support
-will be withdrawn, and removed from the source code, at the next major
-release.
-
-Briefly, original-style extensions should be compiled by including the
-@file{awk.h} header file in the extension source code. Additionally,
-you must define the identifier @samp{GAWK} when building (use
-@samp{-DGAWK} with Unix-style compilers). Otherwise, the definitions
-in @file{gawkapi.h} will cause conflicts with those in @file{awk.h}
-and your extension will not compile.
-
-Just as in previous versions, you load an old-style extension with the
-@code{extension()} built-in function (which is not otherwise documented).
-This function in turn finds and loads the shared object file containing
-the extension and calls its @code{dl_load()} C routine.
-
-Because original-style and new-style extensions use different initialization
-routines (@code{dl_load()} versus @code{dlload()}), they may safely
-be installed in the same directory (to be found by @env{AWKLIBPATH})
-without conflict.
-
-The @command{gawk} development team strongly recommends that you
-convert any old extensions that you may have to use the new API
-described in @ref{Dynamic Extensions}.

-@node Old Extension Mechanism
-@appendixsec Compatibility For Old Extensions
-
-@ref{Dynamic Extensions}, describes the supported API and mechanisms
-for writing extensions for @command{gawk}. This API was introduced
-in @value{PVERSION} 4.1. However, for many years @command{gawk}
-provided an extension mechanism that required knowledge of @command{gawk}
-internals and that was not as well designed.
-
-In order to provide a transition period, @command{gawk} @value{PVERSION} 4.1
-continues to support the original extension mechanism.
-This will be true for the life of exactly one major release. This support
-will be withdrawn, and removed from the source code, at the next major
-release.
-
-Briefly, original-style extensions should be compiled by including the
-@file{awk.h} header file in the extension source code. Additionally,
-you must define the identifier @samp{GAWK} when building (use
-@samp{-DGAWK} with Unix-style compilers). Otherwise, the definitions
-in @file{gawkapi.h} will cause conflicts with those in @file{awk.h}
-and your extension will not compile.
-
-Just as in previous versions, you load an old-style extension with the
-@code{extension()} built-in function (which is not otherwise documented).
-This function in turn finds and loads the shared object file containing
-the extension and calls its @code{dl_load()} C routine.
-
-Because original-style and new-style extensions use different initialization
-routines (@code{dl_load()} versus @code{dlload()}), they may safely
-be installed in the same directory (to be found by @env{AWKLIBPATH})
-without conflict.
-
-The @command{gawk} development team strongly recommends that you
-convert any old extensions that you may have to use the new API
-described in @ref{Dynamic Extensions}.
