If GC_DEBUG is defined then all-upper-case macros will expand to calls to the debug variant of collector functions. So add the configury bit to define GC_DEBUG if the user wants and switch all `GC_` calls to the corresponding macros. libga68/ChangeLog: * configure: Regenerate. * configure.ac: Add --enable-algol68-gc-debug option and define GC_DEBUG accordingly. * ga68-alloc.c (_libga68_realloc): Use the C macro version of the GC function. (_libga68_realloc_unchecked): Likewise. (_libga68_malloc): Likewise. Signed-off-by: Pietro Monteiro <pietro@sociotechnical.xyz>
