Thanks for your report.

Hmm, I can see this is a problem.  Mailine doesn't have this problem
since HAVE_I387_REGS is gone now, and all supported i386 targets
include the floating-point registers by default.  However I intend to
check in a patch shortly that fixes FP_REGNUM_P, since my intention is
to support targets without floating-point registers in the future
again.

I'll see if I can put the same fix on the 5.2 branch.
