I can confirm that there's an issue with a2ps and GCC-15, but the
above messages (and the build log) show only some temporarily problem
with the build dependencies of the build system:

The following packages have unmet dependencies:
 libgccjit0 : Depends: gcc-15-base (= 15-20250203-1) but 15-20250213-1 is to be installed

So I did a build with GCC-15 myself.
The full build log can be found at:
https://people.debian.org/~roland/a2ps_4.15.6-1_unstable_gccexp.log.gz

The end of the error log shows:

parseppd.y:157:1: error: conflicting types for 'yyprint'; have 'void(FILE *, int,  YYSTYPE)'
  157 | yyprint (FILE *file, int type, YYSTYPE value)
      | ^~~~~~~
parseppd.y:53:13: note: previous declaration of 'yyprint' with type 'void(void)'
   53 | static void yyprint ();
      |             ^~~~~~~
