Subject: configure - m4: make CURL_CHECK_DEF ignore leading whitespace on symbol def
X-Git-Tag: curl-7_23_0~134
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a2d4a98ddd2388c42a183a4dbee8befeac5e09f2;p=thirdparty%2Fcurl.git

configure - m4: make CURL_CHECK_DEF ignore leading whitespace on symbol def

When using Sun C compiler the preprocessor somehow inserts an extra space
in front of replaced symbol, breaking CURL_CHECK_DEF macro. To workaround
this, macro CURL_CHECK_DEF now ignores all leading whitespace in front of
symbol substitution result.
