What is limits.h and why is it bothering me...

For the past several weeks, I have tried to compile programs but I keep getting variations of the following: /usr/include/bits/local_lim.h:27: linux/limits.h: No such file or directory The 'limits.h' seems to be the common element. A search of my system shows me 7 different locations (many of them from /lost+found). Do I just copy from one of those into...where? I do not have a linux/limits directory at root. Installing by RPM seems to work fine, but a lot of programs are not available that way...(the latest being Procmeter). All help is appreciated--thanx. System info: SuSE 6.4, AMD k6-2...yada yada yada.
