Sure is, if you insist on running under Windows.  In v1.x, floating point
emulation doesn't work in DPMI mode (which is the *only* mode DJGPP can 
run under Windows).  This is explained in the DJGPP FAQ list (available 
as faq102.zip from the same place you get DJGPP).

You probably have grep compiled with v2.0.  It *requires* a DPMI server 
to run.  Windows provides such a server.  If you want to run it outside 
Windows, get CWSDPMI (the free DPMI server which comes with v2.0), or 
install a memory manager that can provide DPMI services (like 386Max or 
QEMM/QDPMI).
