I compiled zsh on plain RedHad-4.0-sparc which has an old resources.h
that's why I did not notice it.  The patch below should fix it.  I'm in the
process of replacing SunOS 4 to SparcLinux here and as a test I installed
it on a SUN ELC but that's a lot slower than a 386 DX/40 so I do not have
time to compile the kernel on it, I only use binary kernel images, and I
forgot to upgrage the includes.

That compiles on SparcLinux fine, but it may break something else, so
please test it (especially those using UP-UX-10.20, Digital Unix 4.x or
AIX-4.x).

I know this preprocessor trickery is ugly but the alternatives are not much
better either.  We can generate limits with an awk script but it took more
than a year to make the awk script generating signames.h portable.  And for
that we have to find out where are the RLIMIT_ macros defined (that seems
to be always in /usr/include/sys/resource.h but on Linux it is under asm).
