Hello,

I get following with 2.04 libc:

[...]
(TARGET_MACHINE='i686-pc-msdosdjgpp'; srcdir=`cd /devel/djgppwip/gnu/gcc-3.2/gcc; pwd`; \
SHELL='c:/devel/djgppwip/bin/sh.exe' ;\
export TARGET_MACHINE srcdir SHELL ; \
c:/devel/djgppwip/bin/sh.exe ./fixinc.sh `pwd`/include c:/devel/djgppwip/include ; \
rm -f include/syslimits.h; \
if [ -f include/limits.h ]; then \
  mv include/limits.h include/syslimits.h; \
else \
  cp /devel/djgppwip/gnu/gcc-3.2/gcc/gsyslimits.h include/syslimits.h; \
fi; \
chmod a+r include/syslimits.h)

Cleaning up unneeded directories:



At this point NTVDM crashes. My gcc, bash, binutils and several GNU
utils (but not everything) are built with 2.04. Is this known
problem on W2K?

I've made tiny script to help myself to debug it:
----
TARGET_MACHINE='i686-pc-msdosdjgpp';
srcdir=`cd /devel/djgppwip/gnu/gcc-3.2/gcc; pwd`;
SHELL='c:/devel/djgppwip/bin/sh.exe';
export TARGET_MACHINE srcdir SHELL;
gdb --args c:/devel/djgppwip/bin/sh.exe ./fixinc.sh c:/devel/djgppwip/gnu/build.gcc/gcc/include c:/devel/djgppwip/include
----
It setups exact environment for fixinc.sh as if called from makefile
on my box. I add set -x to fixinc.sh too and now I've got following
output from GDB _every time_ I do simple 'r':
1) first 'r' stops after few lines executed
2) second 'r' stops after nothing executed
3) second 'r' executes just like invocation from Makefile
and crashes NTVDM at the end (at varying points, to make it worse:
it maybe any command from last find invocation...)

Well, that seems quite interesting, to put it mildly. Any pointers for
debugging?

TIA,
