True, that is very easy to do.
But one has to wonder why it's not taken care of in the GSL source code.
It would be easy for the GSL developers to check if {{{fprnd_t}}} is
defined or not in the configure script. I guess if there are a large
number of things that might be undefined, then it would get a bit of a
headache.
I think Sage gets a lot harder to maintain, and a lot easier for bugs to
get missed on one platform or another with so many conditional bits of
code.
* We apply readline on some linux versions but not on all OpenSUSE
versions
* We use iconv on Solaris, HP-UX and Cygwin but not Linux or OS X.
* We patch {{{paripriv.h}}} on OS X and Solaris, but in different ways.
* etc etc etc.
I prefer the {{{autoconf}}} approach of actually '''testing''' what is
defined or not, rather than us making exceptions for this platform or that
platform.
Let's say I put code like:
{{{
if[ "x$UNAME = xAIX ] ; then
cp patches/fp-aix.c src/fp-aix.c # or wherever the file needs to go.
fi
}}}
then I've no idea if that is necessary on anything other than AIX 5.3. I
might be able to find someone to test it on the next release of AIX which
is 6.1. (IBM never released a 5.4 or 6.0, so their version numbering is
even stranger than Sage's, which is saying something !!)
My 32-bit machine is too old to run AIX 6.1, which only has a 64-bit
kernel. AIX 5.3 is still officially supported by IBM and will be for a
couple of years. Earlier verisons of AIX are no longer supported by IBM,
so it is probably not worth worrying about earlier releases. But one
should consider AIX 6.1, and the soon to be released AIX 7.0.
