[MITgcm-support] G95 build issue: f2c name mangling

[chris hill]

Mark,

  Can you try changing

  system_time ==> systemtime
  user_time   ==> usertime

  in timers.F and timer_stats.c.

  If I understood Ed correctly that should make the gnu linker happy. If 
it seems to work for you we can try and change it permanently - it 
shouldn't break anything else.

Thanks,

Chris
