Which gcc was used to compile OpenOffice.org?

[Andrea]

Hi,

I am trying to develop an add-in (in C++) for OpenOffice.org Calc, and after a while I have found
out that I need to use the same compiler used to compile OO otherwise anything could go wrong.

http://www.oooforum.org/forum/viewtopic.phtml?t=21536

In my case, exceptions are not caught, but OO terminates immediately like

terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'

I am in Fedora 9, and the compiler shipped is gcc 4.3.0.
How can I find which gcc was used to compile OpenOffice?

Cheers
