Fedora ppc64le toolchain recently changed expansion of the isinf() macro,
which causes the !isinf(LDBL_MAX) assertion to fail when using the LDBL_MAX
value defined by gnulib. On the other hand, it still works correctly when
using the LDBL_MAX value defined by the toolchain.
The -D__SUPPORT_SNAN__ preprocessor flag can be used as a workaround.
A more detailed analysis of the issue is available here:
https://bugzilla.redhat.com/show_bug.cgi?id=1294016#c15
Is this a bug in the toolchain or a gnulib bug?
