gmp-5.0.5 builds and tests Ok on m68k-linux when configured with -ffloat-store
in CFLAGS. There is one "fcmp;fblt" and three "fcmp;fbne" sequences in the
previously failing test case (just the .o file, so excluding libgmp.a). There
are 24 fcmps in libgmp.a, but they are all followed by relational conditional
jumps, none is followed by an equality/inequality conditional jump.
Should I close this as a duplicate of PR323?
