Re: NEC-LIST:NEC, g77, and RH Linux

All-

I've never compiled NEC4 with g77, but have just gone through a round
of making a bunch of custom modifications to NEC2 using g77 and
found one thing: make sure you use the '-fno-automatic' command
line switch at compile time unless you want great gobs of runtime
errors.

The NEC4 code may have been written a bit more explicitly than
NEC2, but it seems that NEC2 depended on the characteristics of the
compiler in use at the time of development (VAX ?) to automatically
SAVE values across subroutine calls. This is not the natural behavior
of g77 and the static behavior must be explicitly turned on with the
command line switch I referenced above.
