Here's a question: *which* limits.h? On my 6.3 system, if I locate
limits.h, I get:
/usr/include/limits.h
/usr/include/c++/4.4.4/tr1/limits.h
/usr/include/linux/limits.h
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include/limits.h
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include/syslimits.h
/usr/share/doc/pam-1.1.1/html/sag-pam_limits.html
/usr/share/man/man0p/limits.h.0p.gz
/usr/src/kernels/2.6.32-279.1.1.el6.x86_64/include/linux/limits.h
/usr/src/kernels/2.6.32-279.11.1.el6.x86_64/include/linux/limits.h
/usr/src/kernels/2.6.32-279.2.1.el6.x86_64/include/linux/limits.h

*sigh* And she didn't have a shield? What *were* they thinking?

       mark "my old shield's in the family room...."
