EGCS in SuSE v6.4

I find myself in a bit of a quandary! I've been using SuSE v6.4 since it came out and have been generally satisfied. However, several of the large software packages that I use for my research are written in FORTRAN and are best compiled in egcs As a consequence I've been playing around with Mandrake 7.2 on an experimental partition, primarily because egcs is included in that distribution (although I have to admit that I would rather use CUPS for my networked printer, but that's a separate issue). Sorry for the long-winded introduction. The question is - can I use egcs from the Mandrake distribution in the place of the stock SuSE 6.4 compiler? Comments will be most appreciated. Thanks in advance
