grep and ctags

[Roland Krause]

Friends, 
on my Solaris (x86) box, the path is set such that a simple grep is
/usr/bin/grep and not /usr/xpg4/bin/grep. 

Now, is there a way to have configure test for that and set a define in
config.h to the path for the grep that supports regular expressions? 

I would be more than happy to modify GrepDialog::slotSearch to include
a path to a regular expression grep. 

Walter, if you tell me what to do I will give it a shot myself. 
Roland
