No.  In fact, the calls already overwrite the DOS memory the pattern
is copied to, on the next call to either function.

Should be, if DOS allows it.  We copy the ffblk data down to dos
memory, do the call, then copy the data back up to djgpp memory.
These functions just call the DOS interrupt services after moving the
data around, so whatever DOS allows, DJGPP allows also.
