Did you look at section 3.6 of the DJGPP FAQ list?  It answers some of 
these questions.

If you refer to RSXNTDJ, the reason is because native DJGPP tools cannot 
produce executables in the Windows format.  The cross-compiler fixes that.

Because Cygwin simulates a Posix system on top of non-Posix Windows.  
Providing all the missing functionality takes lots of code.  (Btw, 4MB
is the unstripped size of the DLL; if you strip it, you are left with 
something like 500KB.)

They are reliable.
