Yes. It cleanly applies to the 5 branch and the 4.9 branch. Let me know how a
build and test cycle goes on both, and I propose to drop it into both.

Should we back-port this fix for gcc 5.2.0 as its current gcc/configure
errornously fails the filds and fildq test for 64-bit with both the legacy GNU

Also, testing with in-line assembly using clang 3.7svn, I get the same behavior
for...

This is due to HAVE_AS_IX86_FILDS not being defined. So basically they made
the clang assembly not backwards compatible with the GNU one.
You can add a check to configure.ac if

Note that configure test does succeed if the '-arch i386' option is also passed
to the assembler. Perhaps the tests aren't fine-grained enough as they are only
done for x86_64

The clang developers suggest the test...

Also changing

fildq (%ebp); fistpq (%ebp)
allows the fildq and fistpq mnemonics to pass at -m32/-m64 on the clang-based
assembler.
