Subject: tests: AC_C_FLEXIBLE_ARRAY_MEMBER result can vary between C and C++.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0f1a2fc63e4d30f825e0a8542673221204c89c84;p=thirdparty%2Fautoconf.git

tests: AC_C_FLEXIBLE_ARRAY_MEMBER result can vary between C and C++.

For example, the native C compiler for Solaris 10 (Sun C in, at least,
the version 5.9 .. 5.15 range) supports C99 flexible array members,
but the matching C++ compiler doesn’t.
