Sorry,

I appologise. I thought I had posted a follow-up to this problem, but I see I 
did not. I started to write it, and must have overlooked sending it.

Once I used the

autoreconf -i -f -v

as documented in the script "autogen.sh" the configure script worked. I was able 
to generate a configure script that generated a Makefile which would build on my 
Solaris machine ok.

I got somewhere on the AIX issue and believe I solved the original AIX problem.

However, I did not copy all of the information from /usr/include/float.h - but 
only that which was missing, it seemed a bit pointless copying loads of stuff 
you don't need, which might actually be wrong on another release of AIX.

BTW, there's a copy of the include file /usr/include/float.h on an AIX 5.3 
system here.

http://trac.sagemath.org/sage_trac/attachment/ticket/10000/float.h

To solve the AIX 'fprnd_t' issue, I think it boils down to:

1) First, one needs a test for 'fprnd_t', which I can do from the configure 
script. I *think* one only needs this.

AC_CHECK_DECLS(fprnd_t,,,[#include <float.h>])

2) Next one needs to check if fprnd_t is defined or not, and if not, use a 
typedef in ieee-utils/fp-aix.c

#ifndef HAVE_DECL_FPRND_T
typedef unsigned short fprnd_t;
#endif


3) Finally one needs to define these in ./ieee-utils/fp-aix.c, if they are not 
already defined, as none were for me.

#ifndef FP_RND_RZ
#define FP_RND_RZ       0
#endif

etc also with:
#define FP_RND_RN       1
#define FP_RND_RP       2
#define FP_RND_RM       3

That is enough to get the code to compile on AIX 5.3, but it is not building the 
library properly - see below. I'm pretty new to AIX, so don't have a lot of 
experience in knowing what these errors might be.

Have you see these sorts of errors on other platforms, and might have a clue 
what they mean?
