Sun Studio 11 compile on Solaris 10 fails "make check"

[Nicholas Oxhøj]

Hi,

I tried compiling gmp-4.2.2.tar.gz on a Solaris 2.10 sun4u sparc using 
the Sun Studio 11 compiler ("cc -V" returns "cc: Sun C 5.8 2005/10/13").

But "make check" failed the "t-get_d" test:

PASS: t-asmtype
PASS: t-aors_1
PASS: t-divrem_1
PASS: t-fat
mpn_get_d wrong on random data

uname -a returns "SunOS fep7 5.10 Generic_118833-36 sun4u sparc 
SUNW,UltraAX-i2"
./config.guess returns "ultrasparc2-sun-solaris2.10"
./configfsf.guess returns "sparc-sun-solaris2.10"

I seem to have fixed the problem by setting "-fsimple=0" in line 3366 of 
the configure script, such that the compiler now generates code 
complying with the IEEE-754 floating-point arithmetic standard.
