You may have figured this out by now but I'll send a message anyway.

You can simply declare the Pascal functions to be pascal functions.  If
you have a routine such as

  procedure foo(a:integer; var b:integer);

you could declare it in your C program as

  extern pascal void foo(int a, int *b);

You can also have C function compiled using Pascal style parameter
passing by using the -p option.  If you have any function in the
code that you keep with the C style parameter passing then use the
keyword 'cdelc' in the function declaration.  Notice that if you declare
a function to be a pascal routine then you cannot pass a variable number
of parameters to it as you can in C.
