Yes, later versions of GCC with DJGPP resolve strcpy to stpcpy 
internally.  I have not looked at the code, but I assume it's some kind 
of optimization strategy based on strings with known sizes. I believe 
this started in GCC4.

Simply add DXE_EXPORT(stpcpy) to the dos/dxe.c file with the rest of the 
DXE_EXPORT table and recompile.  It's possible there may be some other 
functions like this in string.h that you will have to do.
