small problem with SGI compilers, and I still don't understand finding
strsep -- see below

As for the prompt question -- a generic prompt as suggest by Philip Taylor is
much better than something system-dependent.  The same problem should
lead to the same google search on all platforms so we don't end up with 2
FAQ entries for the same underlying problem.

I (slightly) abused your build.sh configuration by compiling with -std=c99 on
Fedora Release 7 (i686, gcc (GCC) 4.1.2 20070502 (Red Hat 4.1.2-12)) and
using system libraries (fewer chances for the compile to fail and less time to
compile):
Not that it should make a difference, but does the standard build.sh work?
I have no problems with OpenSUSE 10.1 (gcc (GCC) 4.1.0 (SUSE Linux))
and 10.2 (gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)) and
-std=c99 -Wall.
debian stable with "-std=c99 -march=i686 -Wall" gives the same error
as Fedora.
Either "-std=g99 .." or "-std=c99 -D_BSD_SOURCE" works.  Following the
definition of strsep thru the header files and glibc sources is like those games
where you get lost in a maze of twisty-turny passages.  Google found some cases
where people gave up trying to get configure to find strsep reliably
and just coded
around it.

Meanwhile, SGI Irix 6.5 complains about:

gmake[1]: *** [GString.o] Error 2

I changed this to an explicit cast to double.  The result seems to work
(builds formats, processes story.tex and sample2e.tex).
