Subject: Dont define __LONG_DOUBLE_128__ unless LongDoubleWidth is really 128bits width.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b2f6f4764e4d7da70b9ed99aa5bbb346018feedc;p=clang

Dont define __LONG_DOUBLE_128__ unless LongDoubleWidth is really 128bits width.
It's not the case on ie. FreeBSD.
