Question: at which version gcc started supporting -D_FORTIFY_SOURCE for c++ files?

[Oleg Pekar (olpekar)]

Hi,
I'm using gcc 4.1.2, it supports -D_FORTIFY_SOURCE option for c files but not 
for c++. I'm looking for gcc version number where support for this option in 
c++ files was added.

Thanks,
Oleg
