libnsl question

[David Relson]

A strange one today...

While debugging with emacs and gdb,  I noticed some odd behavior with the 
step-into  command (ctl-s, ctl-i).  With one executable it works correctly 
and with a different executable, it works as a next (ctl-s, ctl-n).  I 
looked at Makefile to see what was being linked and discovered that the 
relevant difference was "LIBS = -lnsl".  Now I have two versions of a very 
small Objective-C program.  One is linked with nsl and one is linked 
without nsl.  Gdb works normally with executable that lacks -lnsl and works 
incorrectly with the executable that includes -lnsl.

What the heck is libnsl.so.1 (to be precise)?

Any theories why it causes trouble?
