Subject: [clang] Fix broken include_next in float.h
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0ce17ee315fc984449410005febd8b607180456b;p=clang

[clang] Fix broken include_next in float.h

Summary:
The code defines __FLOAT_H and then includes the next <float.h>, which is
guarded on __FLOAT_H so it gets skipped entirely. This commit uses the header
guard __CLANG_FLOAT_H, like other headers (such as limits.h) do.
