Hi:

   I've just found pgcc and pg77 and have a couple of questions.
I'm a physicist working on numerical simulations with fortran programs 
and for the last couple of years I've been using linux+g77 (from
0.5.16 to 0.5.19) in P166 and P200 with very good results.
Looking for info about the reliability of 0.5.21 (0.5.20 was buggy) I
found pgcc-pg77. Now my questions, which are almost exclusively pg77 
oriented.

1)  Is it possible to have a global comparison between g77 and pg77?
I'm particularly interested in points such as speed, accuracy and 
if there are any features covered by one of them and not by the other.

2)  A feature that g77 lacks (at least up to 0.5.19) is debugging
support; has pg77 any debugging support? gdb and ddd have a well 
earned reputation and is a pity not to use them

3)  If I install pgcc and pg77 I infer from the faq that the 
software I have installed will still be up and running. My specific
question is: if I compile with pgcc-pg77 and link against libraries
compiled with gcc-g77 will I have a runable program or some
brain-damaged one?. I have linux 2.0.30, gcc2.7.2.1, libc5.4.33,
binutils 2.8.10.1

Also, if some testing is needed and I'm able to do it let me know.
What I can't do is any developing, my programmer skills are not up
to the job.                       

     Thanks to everybody
