Subject: m4: Use x in order to avoid variable 'x' set but not used [-Werror=unused-but-set... 
X-Git-Tag: curl-7_23_0~116
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=381459fa65a37943417462b32cb312ea9b3c7a62;p=thirdparty%2Fcurl.git

m4: Use x in order to avoid variable 'x' set but not used [-Werror=unused-but-set-variable]

This error could be caused by configure scripts being run with -Werror
-Wall, which would lead to libcurl being detected as unusable.
