A couple of comments specific to AIX about the INSTALL file.

1) The INSTALL file has the information about what to do if you get:

  fp-aix.c:30: error: `fprnd_t' undeclared (first use in this function)

on AIX.

That should not happen any more, as fprnd_t is tested for in the configure 
script. If fprnd_t is not declared, then it gets declared in fp-aix.c So that 
bug is fixed and so personally I think the note can be removed.


2) The INSTALL file says on AIX if you get "ld: 0711-593 SEVERE ERROR:" then to 
compile with -g0.

That will work around the problem, which was caused by IBM making a change to 
the assembler /usr/ccs/bin/as in a patche they released. There are however 3 
options to work around this problem.

 2a) Compile with -g0 as stated. This is by far the easiest, but one is going 
to hit the problem when building lots of software with gcc. So it's not a great 
solution.

 2b) Copy /usr/ccs/bin/as from an unpatched system.
Totally unsupported by IBM of course, but in practice I've found this the best 
fix.

 2c) Use a later set of patches for AIX when this is properly fixed by IBM. At 
this time it's not fixed, but it is acknowledged by IBM, so at some point in the 
future it should be fixed. See
