I just committed a fix to CVS. Basically, /usr/bin/awk on Solaris is 
ancient, so it doesn't support the sub command for substring 
substitution, which is what happens on lines 24, 25 and 26 in the 
diff-prs script. Solaris and other OSes with old awks usually have a 
'nawk' command which is a more modern awk implementation.

I have added the standard autoconf check for awk to the GNATS configure 
setup. This basically checks for gawk, mawk, nawk, and awk, in that 
order (gawk, GNU awk, is generally considered the best implementation), 
and uses the best implementation available in the diff-prs script.

Look at https://savannah.gnu.org/cvs/?group=gnats for instructions on 
checking out the CVS version of GNATS.
