Not easily in any case!

With a new pentium II machine and nothing much except Windows 98
loaded it seemed a good time to try something for which I would
never find enough memory or time on my old machine.

So gcc281s.zip was loaded, (Oct 22, 1998) along with the binaries
and associated GNU binaries, (even acnf212b.zip when a first run
reported it couldn't find autoconfig), and djdev202.zip.

As per instructions, from %DJDIR%/gnu/gcc-2.81/build.djg the
command "sh djmake.sh" started the build process.  This ran into
trouble about six minutes into the build where it was working
on `libgcc2.a'.  The error was different on each run.  From a
full DOS screen, windows snapped it shut so fast that nothing
could be seen.  Once the error reported was "Load error:  no DOS
memory".  Windows accepted 600K as the largest block of DOS
memory it would reserve for the DOS prompt.  Working from a
window rather than full screen, the message:

"This program has performed an illegal operation and will be
terminated.  Exit all programs and then restart your computer."

additional information:

invalid page exception
Fault location:  0028:C00025E6
Faulting component:  VMM[01] +000015E6
Interrupts in service: None

Only once did I notice any error messages in the DOS window,
but that was lost when, in trying to move the windows error
box out of the way, it was accidentally closed.

Finally the build got past that point.  It happened while
I was no longer watching the screen.  Nothing else had been
changed from the previous run which failed.

But the script now went down a blind alley.  Following the
conditional at the target "f77-runtime:" (Makefile: line 1626)
it produced:

entering directory "../gcc-2.81/build.djg/f/runtime"

     "..No rule to make target all"

which is quite true since that directory contains nothing but
three subdirectories.  To find any action, it would have
to enter the directory:

    "../gcc-2.81/f/runtime"

where a Makefile awaits.

Has anyone successfully built gcc 2.8.1 with itself under
DJGPP V2?  I'd appreciate any help.

Incidentally, removing `g77.exe' as a target in the top
level of the Makefile (all.internal:) does not stop fortran
functions from being compiled.

Multiple warnings are issued about "size_t" (and wchar_t)
being defined in <stdio.h> and redefined in <atddef.h>
and "va_list" defined in <stdio.h> and redefined in <stdarg.h>.
All three files are included in "djdev202.zip".  Is the
compiler being too pickey or should these files be protected
from eachother?

Regards,
Frank
