[Rd] extra flags for cc and f77 on alpha (PR#420)

[albrecht.gebhardt@uni-klu.ac.at]

Full_Name: Albrecht Gebhardt
Version: 0.99.0
OS: alpha, osf4.0
Submission from: (NULL) (143.205.180.40)


Im not sure if this is really correct, but it has proven to work.

1. It is always a good idea to add -std1 to DEC cc's flags to force 
strict ANSI language mode. It was neccessary for 0.90.x to compile, 
so I used it for 0.99.0 too
2. I'm not sure if -fpe3 is neccessary for DEC f77, but it seems to 
enable IEEE floating point exception handling (if I understood what 
was said in the manpage). Correct me if I'm wrong.  

Patch below.
