main.c:
#include <math.h>
#include "a.h"

int main(void){
 exception("math.h");
 return 0;
}

a.h:
void exception(char *string);

a.c:
#include <stdio.h>

void exception(char *string)
{
 printf("Exception: %s\n", string);
}
----------------------------------------
dmc main.c a.c
main.obj(main)
 Error 42: Symbol Undefined __exception

If math.h is included in main.c the compiler reports the above error.
According to the latest C standard "exception" is not reserved word nor part
of the standard math library.

If you look in math.h exception is defined as a struct unless you do:

#define _EXCEPTION_DEFINED


Including this define in your code fixes the problem but I'd probably 
choose a different name for your function.
