a9ee20cb9a [CRT:MATH] Import nextafter, nextafterf and nexttowardf from musl 
Note: On Windows, where a long double is the same as a double, nextafterl is the same as nextafter, nexttowardl is the same as nexttoward.
Also nexttoward is the same as nextafter.

f80d978fc0 [CRT] Fix link issues with __ftol2 when compiling for NT6 
__ftol2 is exported from msvcrt on NT6+, not from ntdll for some reason. So native apps still need to statically link _ftol2 and _ftoul2_legacy, but apps linking to msvcrt only need to statically link _ftoul2_legacy (via msvcrtex), when on NT6+.

f637e6b809 [CRT] Implement __ftoul2_legacy 
This is used by CL v19.41+. It replicates the behavior of the inline assembly code that previous CL versions generated. According to tests it works the same as with previous VS versions.

da2a5673e7 [CRT] Fix _matherror and _setusermatherror 
We previously used 2 different versions: one from wine and one from mingw-w64.
The former was used in msvcrt, the latter was statically compiled into the executable. When using MS libs, there is only one _matherr, which is statically linked into the executable and does nothing (it's not really a function for users to be called).
_setusermatherror should only exist in msvcrt and not statically, which wouldn't work at all.
