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?
Yes -- not tested, but the .pool files are identical between the standard build
and my -std=c99 build.

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.
Interesting.  Could it be that Red Hat has a different take on whether strsep is
visible under std=c99?

CC='cc -std=c99 -Wall' ./build.sh > build-c99-Wall.log 2>&1

failed at the same place, and from this build,
source/build/libs/obsdcompat/config.log
fails to detect strsep:

in the glibc changelog there is:

* Wed Oct 03 2001 Jakub Jelinek  2.2.4-19
- fix strsep

http://www.ecos.sourceware.org/ml/libc-hacker/2001-10/msg00001.html
has some discussion of the patch.

It may be that I need to add -D_BSD_SOURCE to get strsep on Red Hat, but
I still don't like the test used by openssh's configure

I'll try this with a different distribution (hopefully Monday).
