[patch] less-444-regcmp-libs.patch

less-444-regcmp-libs.patch (text/plain), 924 bytes, created by Fabian Groffen on 2011-10-23 11:38:45 UTC

When regcmp is in libc (such as on Solaris 10) we obviously find regcmp
in any library we additionally link against that exists, which adds
unnecessary library dependencies.
