1) Cleanup: moved function implementations from win32/include/math.h to win32/include/tcc/tcc_libm.h 2) Added missing math functions: MUSL: asinh(), acosh(), atanh(), scalbn(). My impl: log1p(), expm1(), ilogb(), scalbln(), nexttoward() - now only a few are missing: remquo(), remainder(), fma(), nan(), erf(), erfc(), nearbyint(). 3) Added/defined all missing *f() and *l() math functions. 4) Added functions have short but accurate/fast implementations. 5) Added <tgmath.h> for all platforms. (not too useful, IMO, but is C99 standard).
