mmap isn't a standard C function, it's a POSIX function.  Slight 
difference, but important.

It sounds like you're using the GDC Phobos library--the DMD version 
doesn't have that file.  If you're targeting WinCE, the compiled code 
will probably be linking to the DMD Phobos.  It has all the necessary 
Windows calls in place.  Alternately, you may simply have to move some 
DMD Phobos code into GDC or compile a slightly different set of object 
files.  If it's any help, the GC files needed for Windows are:

     gc.obj
     gcbits.obj
     gcx.obj
     win32.obj

gcstats.obj is required as well, but that should build as a part of 
phobos/std.
