internal.h included after math.h in complex.c
r51313 modified complex.c to include internal.h after math.h, so that ruby/missing.h (included from internal.h) can test whether
M_PI is defined or not in math.h. Unfortunately, ruby/config.h, which is included from internal.h, defines
_LARGE_FILES, which must be defined before sys/types.h is included from math.h. Otherwise, in AIX,
off_t would be incorrectly defined as a 32-bit integer even when large files are used.

There would be a couple of workarounds to fix this problem, but since I am relatively new to the Ruby core, I am wondering what would be the most acceptable way.

- Define M_PI and M_PI_2 in complex.c
- Define _LARGE_FILES not in config.h but in a compiler option
- Include ruby/config.h before math.h but keep internal.h included after math.h in complex.c
- Any other options?
Option 3 looks reasonable if it is allowed to directly include ruby/config.h.
