File: GENERATE_CONFIG_H_VMS_GAWK.COM +$! +$! Gawk like most open source products uses a variant of a config.h file. +$! Depending on the curl version, this could be config.h or curl_config.h. +$! +$! For GNV based builds, the configure script is run and that produces +$! a [curl_]config.h file. Configure scripts on VMS generally do not +$! know how to do everything, so there is also a [-.lib]config-vms.h file +$! that has VMS specific code that compensates for bugs in some of the +$! VMS shared images. +$! +$! This generates a []config.h file and also a config_vms.h file, +$! which is used to supplement that file. +$! +$! +$! Copyright 2013, John Malmberg +$! +$!
