The debug option isn't very helpful, however, I've found the _Perl_ debug 
flag, '-d', used on the first line of autoupdate and autom4te is very useful 
as it allows me to go into debugger mode and I can single step through the 
code. As a result I managed to make this trace:-


  DB<2>
File::Glob::csh_glob(c:/usr/lib/perl/lib/5.6.0/os2/File/Glob.pm:164):
164:                delete $entries{$cxix};
  DB<2>
File::Glob::csh_glob(c:/usr/lib/perl/lib/5.6.0/os2/File/Glob.pm:165):
165:                return undef;
  DB<2>
Autom4te::General::CODE(0x26e548)(c:/usr/local/share/autoconf/Autom4te/General.pm:110):
110:          rmdir $tmp
111:            or carp ("$me: cannot remove $tmp: $!\n"), _exit (1);
  DB<2>
Autom4te::General::CODE(0x26e548)(c:/usr/local/share/autoconf/Autom4te/General.pm:116):
116:      close STDOUT
117:        or (carp "$me: closing standard output: $!\n"), _exit (1);
  DB<2>
Autom4te::General::CODE(0x26e548)(c:/usr/local/share/autoconf/Autom4te/General.pm:119):
119:      _exit ($exit_status);
  DB<2>
autoupdate.: cannot close autom4te --language=autoconf 
--include=c:/usr/local/share/autoconf
 --trace AU_DEFUN:'AU:$f:$1' --trace define:'AC:$f:$1' --melt /dev/null |:
 at c:/usr/local/bin/autoupdate. line 185


So it looks as though the code is actually failing here:-

share/autoconf/Autom4te/General.pm 


I'm no Perl expert, and have no idea what is going on here so can anyone 
explain why it's failing?
