gcc bounds checking

[Orion Poplawski]

Looks, looks like gcc can do certain compile time bounds checking (probably 
for ages but I'm slow) and emits warnings like:

In function 'strcpy',
     inlined from 'New_psimage_Ctrl' at psimage.c:357:9:
/usr/include/bits/string3.h:107:3: warning: call to __builtin___strcpy_chk 
will always overflow destination buffer

Unfortunately, it's only a warning and as a typically lazy packager who 
packages software with lots of compiler warnings, I missed this until it 
caused a runtime fortify error check.

So, perhaps the gcc folks can say why this isn't an error?

And perhaps would could grep though all of the build logs for this one?
