[MITgcm-support] compile-run error due to gcc update?

[Sergey Vinogradov]

Hi:

After recent gcc update, I'm getting compile-run error on my 
previously-working configuration. Error is something like this:

------------------------------------------------------------------
Makefile:1167: warning: ignoring old commands for target `write_local_rs.F'
...
Makefile:1207: warning: overriding commands for target `write_myfield.F'

------------------------------------------------------------------
My file SIZE.h is on its place, as well as other configuration files. If 
it is related to the gcc update, do you know how to fix it? The compiler 
and some OS updates are the only difference between working and 
non-working code. New gcc is 3.4.3 (see below)
