Problem building epics base-3.14.6 with recent gcc on linux

[Chip Piller <piller@sns.gov>]

Hi,
I've tried to build epics base-3.14.6 on linux, results are:

gcc 3.3.2:  Success.
gcc 3.3.4:  Failed for both 3.14.6 and latest CVS.
gcc 3.4.2:  Failed for both 3.14.6 and latest CVS.

Any info/suggestions for using recent gcc?

Thanks,
Chip Piller
