Raw Blame History

These changes are mostly inherited from previous iterations
of gnulib-printf-in-glib.
Here are explanations for some of them:
* g-gnulib.h is a minimal replacement for gnulib config.h
* gnulib_math.h is a processed copy of gnulib math.in.h
We can't keep it named math.h, since we need to include
both the system math.h and this header in some places.
* gnulib_math.h needs _GL_ATTRIBUTE_CONST, put it directly
there instead of getting it from config.h
Also, instead of copying _GL_FUNCDECL_RPL and _GL_WARN_ON_USE
we simply include headers where these macros are defined.
* isnan source files get extra includes, in gnulib these
were probably handled by makefiles and/or configure scripts
* glib has a test result named HAVE_LONG_LONG instead of HAVE_LONG_LONG_INT,
so make the code use that
* One of the goals of using this gnulib implementation in glib is
to have C99-compliant 3-digit exponent, therefore gnulib
ifdefs that *disable* that behaviour are altered to keep it enabled.
Another possible location for such a change is where %n use is
being enabled or disabled. That, however, is not activated anyway,
because this code is made not to use snprintf
* glib has G_MAXSIZE instead of SIZE_MAX, so use that
* The code is made to use glib alloca header
