[nhc-bugs] Portability issue with grep -y

[Wolfgang Lux]

Hello!

I wanted to report just another problem. The scripts nhc98, hmake, and 
tprofrel
use grep -y to perform a case insensitive comparison. According to the 
man
pages on Mac OS X, -y is an obsolete synonym for -i. Even worse, the 
grep on
Solaris 2.7 does not even understand this option.

Here is a patch to replace -y by -i:
