The way command lines are passed in C, you declare the `main' function as
taking arguments. These are traditionally called `argc' for the number of
args, and `argv' as the array. So it really should look like:

int main (int argc, char *argv[])
{
   /* Do things with argv[x] */
}

The `__crt0' ones are for the library's internal use, and probably won't
work on other compilers or even future versions of DJGPP.

Actually, even most DOS C++ compilers have that kind of restriction. Isn't
DJGPP great?

P.S. There is also a Pascal compiler for DJGPP, though it doesn't have most
of the features of Borland's.
