From: Benno Schulenberg Date: Wed, 23 Dec 2015 09:39:50 +0000 (+0000) Subject: AC_CHECK_HEADERS_ONCE() is very special cannot be conditionalized. X-Git-Tag: v2.5.1~39 X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=454f6ebb976b808a078ff66ff01abb76b3209f18;p=nano.git AC_CHECK_HEADERS_ONCE() is very special cannot be conditionalized. Use plain AC_CHECK_HEADERS() instead, so ./configure will not check for magic.h and zlib.h when --disable-libmagic is given.
