I slightly modifed Charles patch so that the changes were only executed if
on a Win NT / 2000 / XP machine, this way I can also use the same LIBC and
code on the Win 98 box.

I can also now build LIBC without restarting every one or two minutes, but I
get the odd NTVDM memory error. The previous time I built LIBC on the Win 2K
box I did not count the number of times I had to re-start the make as it was
to many and I gave up counting.

My LIBC build test:
    Start make #1:  3:36 PM
    Stop m,ake #1: First NTVDM application error with "The instruction
asn"0x0f04c7a9" references memory at "0x021bcf20"./ The memory could not be
written.

    Start make #2:  3:38 PM
    Stop make #2:  3:42 PM  - no errors or any messages the build just
stopped.

    Start make #3:  3:42 PM
    Stop make #3  3:46PM  -SIGSEV and a NTVDM memory error. See screen dump
below.

    Start make #4  3:47PM
    Stop make #4  3:52PM  - NTVDM memory error.

    Start make #5  3:59PM -
    Stop make #5  4:05 PM  - Zoninfo make posix error. See screen dump below

    Start make #6  4:08PM -
    Stop make #6  4:10PM stoped again due to zoneinfo issue with


Overall even with the number of crashes building LIBS it is now feasable for
me to re-build LIBC on the Win 2K machine with the patch from Charles. I am
looking forward to testing a combined Win 9x and 2K patch when it arrives on
both Win 98 and Win 2K.

Does this show that I have a program somewhere where I have not re-built
with the SBRK patch in crt0?

This is a fstat failure. I am now investigating more info and examples to
follow.
