First, you should append -lstdcx -liostream before -lm (to link in the 
C++ class libraries when you compile a C++ program.  Without this, you 
will get unresolved externals.

This program uses Borland-specific extensions to C, like the _AX 
pseudo-register variables and the MK_FP macro.  These things are done 
entirely different in DJGPP.  To learn how, please download the file 
v2/faq201b.zip from the same place you get DJGPP and read chapter 18 of 
the FAQ list.
