Re: Right BCC version to use ?

Hello,

I am afraid moving the current build chain to another compiler is too 
ambitious... and selecting another "exotic" compiler would not bring us 
back into the mainstream...

Back to the initial question, I finally moved to your bin86/dev86 fork 
by cloning your GIT repository. I added a .gitignore to have a more 
clear view on "git status" when doing some changes, please find it 
attached as a patch proposal (big things start with little steps).

Regards,

MFLD

A big difference between BCC and GCC is that BCC includes a C library and headers whereas GCC is only a compiler and requires a C library to be built separately. That means I can't fix issues with the C library without bringing the whole thing along.
