This may be a M$-specific function.  Please describe its purpose
and we'll try to suggest a DJGPP equivalent.

If its name is in any way indicative, however, it may not even be
necessary:  under protected mode in DJGPP there are no segments;
all memory is pooled into what is essentially one large segment.
This is also why MK_FP(), etc., are unecessary under DJGPP.  If
'segread()' is indeed such a function, you may want to read the
DJGPP Frequently Asked Questions list (available as v2/faq201b.zip
from your local SimTel mirror) for the various ways in which DPMI
can affect porting of 16-bit programs.
