.gprc

[Ilya Zakharevich <ilya@Math.Berkeley.EDU>]

a) is it *necessary* to remove all the whitespace from the lines in
   .gprc before processing?  Is not it fortran all over again?

   [Try putting something like this there: #if stable foo=bar]

b) It is very convenient to have #if VERSION; however, it is not
   documented that this directive kills all but with the bleeding
   edge GP/PARI.  It should be supported in the stable branch too to
   become useful.  (Maybe it is the latest stable branches)

c) Is it designed that an unrecognized line in .gprc kills GP/PARI?
   Printing a warning and skipping it looks like more useful directive.

d) It is possible to get an array [2,4,5] for GP/PARI version 2.4.5
   from the GP/PARI API?  Then one could delegate version-dependent
   processing to the read() directives...
