Hello all...

Recently, I've been trying to build a cross (SunOS / Linux) --> MS-DOG (DJ)
compiler, and am getting nothing but headaches.  For the life of me, I
cannot seem to generate a compiler (for either Sun or Linux) which builds
a DJ compatible object, or link DJ generated objects, or build a DOS .exe
file.

Yes, I have all of DJ, and have been reading FAQs and READMEs.  I have
'djcrx200' kit, also.  What I *think* that I need is the magic configuration
option to generate things (i.e. --target=i486-xxx-xxx).  I've tried all
kinds of incantations of this, tried studying the dj source tree itself, etc.

So far, the best I can get is .o files that 'file' reports as
'80386 COFF executable not stripped - version 30821', which is the same as
it reports for the DOS based DJGPP, but still won't link up.  Get linking
problems such as (depending upon the version that I most recently
expirimented with):

i486-coff-go32-ld: warning: cannot find entry symbol _start; defaulting to 000010a8
/home/soft/nleroy/devel/gcc/sparc/i486-coff-go32/lib/libc.a(_main.o)\
    (.text+0x1a):_main.c: undefined reference to `djgpp_last_ctor'

I also seem to be having problems with the leading '_' on symbols --
DJ seems to create _main, but my 'main' is just plain old 'main'.

Please PLEASE, if anybody out there knows the magic incantation, please
enlighten me.  Thank you *very* kindly in advance.

-Nick
