[Help-gsl] Installing GSL 1.6 on AIX

[Donald Frederick]

I'm trying to install GSL 1.6 on AIX 5.3 OS machine, with gcc/xlc. xlc 
is IBM's C compiler, and the option for strict ANSI-compliancy is "c89".

I have run configure with either:

./configure --prefix=/usr/local/apps/gsl/gsl-1.6 --disable-shared

for using gcc
or
./configure --prefix=/usr/local/apps/gsl/gsl-1.6 CC=c89 --disable-shared

I encounter problems in the IEEE utilities directory:

for gcc:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -g -O2 -c fp.c -o fp.o
In file included from fp.c:22:
fp-aix.c: In function `gsl_ieee_set_mode':
fp-aix.c:30: error: `fprnd_t' undeclared (first use in this function)
fp-aix.c:30: error: (Each undeclared identifier is reported only once
fp-aix.c:30: error: for each function it appears in.)
fp-aix.c:30: error: parse error before "rnd"

for c89:

c89 -DHAVE_CONFIG_H -I. -I. -I.. -I.. -g -c env.c

       /bin/sh ../libtool --mode=compile c89 -DHAVE_CONFIG_H -I. -I.

Any suggestions would be appreciated.
