Subject: Expand #include_next in float.h from mingw to _msc_ver.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3030066ef0a6b291173691ec3388b5f590d06e68;p=clang

Expand #include_next in float.h from mingw to _msc_ver.

A test for this is checking if this compiles:

    #include <float.h>

    inline bool IsFinite(const double& number) {
     return _finite(number) != 0;
    }

That depends however on either mingw or msvc being installed, and
chapuni tells me there might be issues with float.h on mingw, so
no automated test is added.
