To: djgpp AT sun DOT soe DOT clarkson DOT edu

Hi!

I would like to ask a question about the file djgppstd.h. 
I have used DJGPP several times now to compile UNIX-programs on my PC,
and it works wonderful. However, quite often I have problems with conflicting
declarations of functions. E.g., there are programs that declare somewhere

void exit();

after having included djgppstd.h as well (via stdio.h or some other headerfile).
There exit is declared as: void volatile exit(int); which is incompatible
with the other declaration. I have solved this by commenting out the declaration
in the program, but it I was wondering why these functions have the type
qualifier `volatile' in djgppstd.h. E.g., on my Iris Indigo the programs
compile without problems, because the standard-headerfiles declare exit simply
as void.
Sorry if this is a faq, I have started using DJGPP two weeks ago...

Thanks for your answers,

Erik
