With changes from my version of gcc431s2.zip and current CVS version of
DJGPP v2.04, GCC-4.3.1
should builds as Cygwin to DJGPP cross-compiler without big problems
(Languages: C, Ada, C++,
Fortran, Objective C and Objective C++). No need for --with-sysroot at all.

GCC Configure options
--target=i586-pc-msdosdjgpp --prefix=/usr/local --disable-nls
--disable-werror
--enable-languages=c,c++,fortran,objc,obj-c++,ada"

I at first bootstrapped GCC-4.3.1 (C and Ada only) as native compiler
for Cygwin and used it for building cross-compiler.

Tried to run testsuite. Seems to be mostly running OK except of on of
fixincludes which requires autogen.
It is however very far from being complete and I perhaps will not want
to wait several days for it to finish.
I also have doubts about whether I can believe results of testsuite as:
    /cygdrive/c/djgpp/bin/false.exe && echo Failed
shows failed. Similary the return code in Cygwin seems to be 0 even in
case of SIGABRT from DJGPP
executable.
