I tried to build gsl-1.14 using gcc 4.2.4 on an IBM RS/6000 running AIX 5.3.
The build failed with:
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

I gather this is a known issue, and the INSTALL file tells one how to get around
this. But would it not be possible to take care of this in the configure script
by checking whether 'fprnd_t' is defined or not? It just seem to me that that is
one of the advantages of autoconf, yet it is not being used to detect this problem.
