Subject: libstdc++: Add parentheses around _GLIBCXX_HAS_BUILTIN definition
X-Git-Tag: basepoints/gcc-16~1904
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=57f65c5c027c7c075c2773a857304f341b9dea1a;p=thirdparty%2Fgcc.git

libstdc++: Add parentheses around _GLIBCXX_HAS_BUILTIN definition

This allows _GLIBCXX_HAS_BUILTIN (or _GLIBCXX_USE_BUILTIN_TRAIT) to be
used as part of a larger logical expression.

libstdc++-v3/ChangeLog:

	* include/bits/c++config (_GLIBCXX_HAS_BUILTIN): Add parentheses.
