Snapshot 20040225: make hangs/errors out

[Brian Ford]

Ok, I haven't been following this thread, but I thought I'd try to help
debug.  Somebody tell me if I found a clue, or I'm just being stupid.

Under a current, debugging enabled, cvs compiled cygwin1.dll:

$ uname -a
CYGWIN_NT-5.1 fordpc 1.5.8(0.111/4/2) 2004-03-02 12:22 i686 unknown
unknown Cygwin

using the attached b.sh script and Makefile, I see the following output:

[snip]
: End 30.pp 1
: Begin 0.pp † 1+1‡
[snip]
: End 30.pp † 1+1‡
: Begin 0.pp † † 1+1‡+1‡
[etc]

hence, the env dump in the script.  Is it just too late in the day for me,
or is there environment corruption at play here?

This is very easy to reproduce, and it changes with minor changes to the
script.
