Re: Texinfo 7.2.90 build with mingw.org's MinGW: tta compilation

The following problems are with compilation in tta/

     d:/usr/bin/gcc.exe -DHAVE_CONFIG_H -I.  -I./parsetexi -I./convert -I./main -I./structuring_transfo -I. -DDATADIR=\"d:/usr/share\"  -DSYSCONFDIR=\"d:/usr/etc\" -I../gnulib/lib  -I../gnulib/lib -DPATH_SEP=\":\" -DEMBED_PERL -Id:/usr/include -s -O2 -DWIN32 -DPERL_TEXTMODE_SCRIPTS -DUSE_SITECUSTOMIZE -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DUSE_PERLIO -fwrapv -fno-strict-aliasing -mms-bitfields  -MT ctexi2any-texi2any.o -MD -MP -MF .deps/ctexi2any-texi2any.Tpo -c -o ctexi2any-texi2any.o `test -f 'texi2any.c' || echo './'`texi2any.c
     <command-line>: error: expected identifier or '(' before string constant

   This is because texi2any.c includes <windows.h> which uses DATADIR.

Here's a simple patch to solve this:

--- tta/C/texi2any.c~0	2026-01-01 20:44:40.000000000 +0200
+++ tta/C/texi2any.c	2026-01-14 17:25:26.663585700 +0200

Next a couple of places where a missing dTHX causes compilation
errors:

 }
 

And after all that, the tree finally builds successfully.  Testing
will begin tomorrow; probably again lots of fun!

Thanks.
