Steve -
  Worked for me -- but I had to create E:\tmp. A few clues about my
setup:

F:\cygwin == /
E:\ = /e
$HOME = /e/Users/cwilson

I ran cpan as 'cwilson', building in /e/Users/cwilson/.cpan/*.  So, the
'CURRENT DRIVE' was E: even though perl is installed into /usr/local
(F:\cygwin\usr\local).

CYGWIN LIST:

I tracked down the problem: the choose_temp_base() routine in libiberty
(which is linked by dllwrap.exe) defines '\\' as the path separator on
all _WIN32 platforms. This routine checks the environment variable
$TMPDIR, $TMP, and $TEMP, followed by {DIRSEP}tmp, and
{DIRSEP}usr{DIRSEP}tmp. So, in my case $TEMP=/tmp. Then, the routine
adds {DIRSEP}ccXXXXXX where 'X' is a digit.

Therefore, '/tmp\ccXXXXXX'.

To whom should a patch for libiberty be sent?
