 * QA Notice: Installing libtool files (.la) without corresponding static libraries!
 *   /usr/libexec/gcc/x86_64-pc-linux-gnu/12/liblto_plugin.la
 * QA Notice: Found the following implicit function declarations in configure logs:
 *   /var/tmp/portage/sys-devel/gcc-12.3.9999/work/build/x86_64-pc-linux-gnu/libgfortran/config.log:4143 - fpsetmask
 *   /var/tmp/portage/sys-devel/gcc-12.3.9999/work/build/x86_64-pc-linux-gnu/32/libgfortran/config.log:4235 - fpsetmask
 * Check that no features were accidentally disabled.

this is correct, fpsetmask is not present on GNU systems.

LIBGFOR_CHECK_FPSETMASK has correct includes for other platforms.
