My main problem seems to be in building the cross libraries.  I don't need
them, so how do I surpress their builds so that the "make install" ( or
"make install-gcc-cross" ? ) command will work for the executables?

Here's what's happened today...

I deleted my entire gcc & binutls source directories and started from
scratch.  I think I had polluted the build system with too many failed
attempts.

First I rebuilt binutils 2.9.1 with these settings (all one line):

sh configure --prefix=/djgpp/cross --program-prefix=h8300-hms-
     --host=i386-pc-msdosdjgpp --target=h8300-hms

I had to use the gnu version (which seems to support DJGPP just fine)
because the zip file found via www.delorie.com/djgpp did not contain the
cross-tools specific files.  Was this intentional or an oversite?  Other
than a small hiccup when I ran "make install", everything seems to be in
place ( had to run "make install" in each subdirectory instead of from the
main source directory).  This resulted in the list of files at the end of
this message.

I then switched to the gnu/gcc-2.952 directory and went to work on crossGCC.
I used these settings (all one line):

sh ./configure --prefix=/djgpp/cross --program-prefix=h8300-hms-
     --host=i386-pc-msdosdjgpp --target=h8300-hms --disable-shared
     --enable-cpp --enable-languages=c,c++  --with-newlib

The following were new on this attempt, but it didn't make any difference
(the problem remained the same):

    --disable-shared --enable-cpp --with-newlib

The configuration went smoothing (no problem with replacing "ln -s" this
time).  I then ran "make cross".  Part way through the process I started
getting errors about not being able to find h8300-hms-ar, etc.  I stopped
the build and dropped all the cross-tools into the main bin directory (I'm
sure there's a switch to fix this, what is it?).  I restarted "make cross".

I received a bunch of these errors:

     ./libgcc2.c:995: warning: right shift count >= width of type

Is this normal?  Since they are only warning errors and I don't care about
the runtime libraries, I didn't worry.  However, later on a fatal error
occurs:

END DUMP ----------------------------------------------------------

I looked inside the problem file.  The first parameter IS 'size_t'.  Perhaps
a redefinition earlier in the build?

In desperation I tried to copy xgcc.exe and related executables manually,
but when I tried to use the cross-compiler it failed.  It didn't pick up the
cross-tools properly.

Here's the files as placed by binutil's "make install" (before gcc "make
install").  The executables in 'h8300-hms\bin' are identical to those in
'bin'.  Is there a purpose to the duplicate files?
