tinycc/win32/include/math.h
grischka ea82d0826d tccpp: cleanup target-os defines 
moved target_machine defines to the <target>-gen.c files.

Also:
- c2str.c moved into conftest.c
- tccdefs.h ; defined(__TINYC__) && !defined(_LOCORE) removed
  (in tinycc __TINYC__ is always defined and _LO... is never.)
- stddef.h : too many #ifdefs, removed
- tccgen.c:stabs: support win32 long doubles aka doubles.
- win32: math.h/tcc_libm.h: fix pointer mismatch in modfl
- tccpp.c: increment include_stack_ptr after the file was
  actually found otherwise it would print
  "in file included from <itself>: file not found..."
