Runtime security/memory checks for gcc/gdb

[guy keren]

i never performed a thorough "head-to-head" comparison between the two. 
valgrind has a few limitations - i didn't check if purify can overcome 
them or not. if it can - it could be a reason to use both of them. i 
think i did once check a program, that had a bug that valgrind didn't 
manage to identify, with pufiry, and it didn't report anything better 
then valgrind did for that case. this is of-course still not a good 
enough test.

on one occasion, there was an application that failed to run under 
purify on windows (it looked like some problem with purify - it's not 
that purify reported errors in the application) - and after it was 
ported to linux - valgrind managed to run it there. i know this is 
comparing apples to oranges plus it being anecdotal evidence,- but it 
was enough for me to get more assurance with valgrind's abilities.
