* Fix typo in acinclude.m4 fs_old_*flagsDan McGee2012-11-27

* Do not enable _FORTIFY_SOURCE without optimizationAllan McRae2012-08-01
| | | | | | | | | | | | | | With glibc-2.16, using -D_FORTIFY_SOURCE requires that optimization (-O) be used or it will prodice a warning message. Enable -Werror in our test for _FORTIFY_SOURCE support to catch when a users specifies CFLAGS without optimization. The line to set CFLAGS="" when no CFLAGS are specified (either due to being unset or geniunely empty) is required as autoconf will use "-O2 -g" for its tests by defult when CFLAGS is unset, but will not add them to the CFLAGS used...
