Excuse the size of the file below - you can ignore most of it.
Down near the bottom of the file there is a function called DoLocking
which calls Allego style macros for locking code and data. It causes a
general protection fault because if I comment it out the problem
disappears. Any sugestions?
#define START_FUNC(x) void x##_start(){}
#define END_FUNC(x) void x##_end(){}
#define LOCK_FUNC(x) _go32_dpmi_lock_code(x##_start,(long)x##_end-(long)x##_start);
#define LOCK_DATA(x) _go32_dpmi_lock_data(x,sizeof(x));
