Subject: * libtool.m4 (AC_CHECK_LIBM): do not set MATHLIB or AC_SUBST it,
X-Git-Tag: release-1-2f~127
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2e6d9dc7a788d1bc6dea49c6e43bacd31615ae49;p=thirdparty%2Flibtool.git

* libtool.m4 (AC_CHECK_LIBM): do not set MATHLIB or AC_SUBST it,
this has a negative side-effect of causing automake to add MATHLIB
to every single Makefile.  Let's use plain AC_CHECK_LIB, so that
LIBS get set, until we find a better alternative
* *demo/Makefile.am: remove $(MATHLIB)
