Subject: (AC_TRY_CPP): Use "" instead of '' when setting ac_try; we need one level
X-Git-Tag: fsf-origin~215
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f42abbab265d7d7b1f18b99fedad76056f7ee1f2;p=thirdparty%2Fautoconf.git

(AC_TRY_CPP): Use "" instead of '' when setting ac_try; we need one level
of expansion there for $ac_cpp, then AC_TRY_EVAL does one more for its the
expansion of $ac_cpp.
