Subject: [PATCH] setup.py: Explicilty use C99 for preprocessing

GCC 15 uses -std=c23 by default, which causes pycparser to error out
with "pycparser.plyparser.ParseError:
/usr/lib/gcc/x86_64-pc-linux-gnu/15/include/stddef.h:450:31:
before: nullptr_t". As pcyparser only supports completely C99,
this shouldn't be an issue.
