Ok, concerning gnatgpr, maybe a specific option could ask to get
run-time information ..

Yes, in fact gnatgpr-0.25 is based on a modified GNAT GPL 2008 Ada front

Thanks for your propositions, i'll had them ...

I still use over  Ada compilers and i still prefer GNAT error messages ...

Thanks for your feedback, it will try to add support to windows
platforms. ..

nice ;-)

ok, thanks anyway

i'll have a look to see if those checks could be easily unplugged,
 i don't need them too...
