Hi Iztok,

thanks for the various error reports! I'm investigating them at the
moment. As for the above, it is true that many compilers allow
differing names in def/mod files. I should be able to easily modify
gm2 to follow this behaviour, and perhaps have a switch for the
stricter rules which you are currently seeing. I took this course of
action after an experience (tracking down a bug) which cost me a day
or so when I was a relative newcomer to M2. Effectively I switched x,
y coordinates..

Proposal:

  (i)   modify GM2 to allow differing parameter names def/mod
        by default
  (ii)  introduce new switch -Wpedantic-param-names which enforces
        same name parameters in def/mod files.

Any comments from anyone?

Thanks,
Gaius
