*	Don't use absolute paths for gawk and cpp.	Kaz Kylheku	2022-03-18	2	-5/+6

*	Ensure we pass -- before non-option arguments.	Kaz Kylheku	2022-03-18	1	-2/+2
\| \| \| \| \| \| \| \|	This is necessary even though our option processing has itself recognized the end of options. The reason is that we do not pass through -- to the list of awk options. (We cannot, because we add options after the awk options like this: $awk $awk_opts -f $tmp_file").
*	Fix broken options quoting system.	Kaz Kylheku	2022-03-18	2	-11/+15
\| \| \| \| \| \|	Unquoting can't just be done with an interpolation into the command line; we have to construct an entire command as shell syntax and eval the whole thing.
*	Rename shell_escape and syntax functions.	Kaz Kylheku	2022-03-18	1	-12/+12

*	Missing quoting in --prepro-only case.	Kaz Kylheku	2022-03-18	1	-1/+1

*	Protect against sed mistaking argument as option.	Kaz Kylheku	2022-03-18	1	-1/+1
\|
*	Test -f option.	Kaz Kylheku	2022-03-18	3	-1/+14
\| \| \| \| \| \| \| \| \|	Bugfix: because the preprocessed version of the file is in a temporary directory, #include "..." looks for files in that directory. We must tell the preprocessor to look for include files in the original directory. In the case when the awk script comes from the command line, we already took care of this by pointing the preprocessor to $(pwd).
*	Handle quoting properly.	Kaz Kylheku	2022-03-18	2	-5/+20
\| \| \| \| \| \| \| \|	The problem is that if $var holds escaped syntax, we cannot just use it as command $var; the quotes become part of the argument. We must get the shell to process the quoted syntax, which requires eval. For this we define a function which lets us do command $(syntax "$var").
*	Add --prepro-only option.	Kaz Kylheku	2022-03-18	2	-5/+19
\|
*	Define __posix__ if -P or --posix option used.	Kaz Kylheku	2022-03-18	2	-0/+13
\|
*	Define __bignum__ if -M or --bignum option used.	Kaz Kylheku	2022-03-18	2	-0/+13

*	Add __gawk__ predefined preprocessor symbol.	Kaz Kylheku	2022-03-18	2	-3/+13
