Avi Halachmi (:avih) 9c52ba48b3 win: math.h: fix fpclassify/signbit/etc - use C instead of broken asm ... The asm code cannot currently be used with tcc since tcc doesn't support 't' constraint. Use inline C implementation instead, place it win32/include/tcc/tcc_libm.h, and include it from win32/include/math.h. Since fpclassify now works, it also fixes few other macros which depend on it. Implicitly fixed: isfinite, isinf, isnan, isnormal. The implementations were taken from musl-libc rs-1.0 (MIT license). musl-libc: http://git.musl-libc.org/cgit/musl/tree/src/math?h=rs-1.0 license: http://git.musl-libc.org/cgit/musl/tree/COPYRIGHT?h=rs-1.0		2015-11-07 22:18:46 +02:00
