Subject: curl-compilers.m4: enable vla warning for clang
X-Git-Tag: curl-7_55_0~177
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=783ce023a54cde30f9b3597554d65e0d24aa2655;p=thirdparty%2Fcurl.git

curl-compilers.m4: enable vla warning for clang

Previously, that warning was only implicitly active in C90 mode.
Enable it unconditionally as already done for GCC.

Closes https://github.com/curl/curl/pull/1578
