So then he *is* using a libc with debug information, or at least the dynamic 
loader library. I debugged inside the dynamic loader library, but using the 
Disassembler Window of RHIDE (was needed to find a bug in gcc 2.7.2.3 that 
made the dynamic Turbo Vision for Linux crash).
Additionally: at least in my system the dynamic loader doesn't call libc at 
all so then is using some inline version of strncmp or was just removed in 
glibc (wich I use).
