Thanks for this report. I understand that -mlong-double-64 is no longer
the default on Linux/PowerPC since gcc-4.1 (2006).
Does the test failure go away if you change in lib/float.in.h the
condition
(defined _ARCH_PPC || defined _POWER) && defined _AIX
to
(defined _ARCH_PPC || defined _POWER || defined __ppc__ || defined
__powerpc__)
and adjust m4/float_h.m4 to set FLOAT_H=float.h and REPLACE_FLOAT_LDBL=1
(like it is done for AIX)?
