Richard & Charles,

I may have stumbled onto some issues with the file utilities 4.1 rm.exe
(don't know if 4.0 also fails) on XP which have come to light when I have
been trying to build GCC 3.2 or trying to rebuild it. I will not have time
to to look at these two issues for a few days and as such I thought I should
let you know about them in case you have ideas or have seen these before.

I am in the process of upgrading to GCC 3.2 and the latest LIBC. The file
utils is 4.1 from 11-June-2002. I suspect that both issues are 2K/XP
specific until someone else lets me know otherwise.

PROBLEM 1 - RM.EXE SIGABRT
--------------------------------------
While re-building GCC 3.2 I noticed that I was not rebuilding some of the
exe files as the build date of a few of the exe files had not been updated.
On further investigation I found that the rm.exe caused a SIGABRT when
rm.exe -rf was called four times, the other times it worked okay when "make
clean" was executed.

I have been able to reproduce the problem on XP (I have not tested this with
any other OS's) if I setup the following directory structure and try to do
delete the directory and all of it's contents with a rm -rf ( i am assuming
this is what is the combo does).

Test directory setup:
    -Created a test directory C:\dj204\test
    -Created a sub directory C:\dj204\test\test
    -Created one file in the subdirectory C:\dj204\test\test\test.c

(simplified):
