My "broken setup" was caused by trying to upgrade to 5.8.8 from 5.8.7.
I ran into incompatibilities and decided to re-install & update the modules from
scratch. I 1st removed "site_perl" then installed 5.8.8. I then used
the CPAN to upgrade itself then the new "update" command to bring my
module list back to current. After some manual installs to get around
cygwin-specific ".dll" replacement issues, I'm only left with "Image::Magick"
that won't update. Fails with many errors, starting with bad compiler options.
Calling my "setup" broken after I detailed on p5p steps to fix it
seems unnecessarily confrontational, but this is the cygwin list....1/2 :-)

At least I know what it is "supposed" to look like. What I see instead is:
> gdb perl
GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special)
This GDB was configured as "i686-pc-cygwin"...Minimal symbols from perl.exe...
(no debugging symbols found)
(gdb) run -e'print 1'
Starting program: /usr/bin/perl.exe -e'print 1'
Program received signal SIGSEGV, Segmentation fault.
0x610b48b6 in pthread_key_create () from /usr/bin/cygwin1.dll

As you noted in your next note, this 2nd problem seems(?) to be duplicable
outside of cygwin.

Good suggestion. Hadn't thought of that. Unfortunately
rebaseall fails as well:
> rebaseall
ReBaseImage (/usr/bin/cygiconv-2.dll) failed with last error = 6
Any other ideas? I tried checking the rebaseall & rebase manpages, but
couldn't find anything referencing "error = 6" (no manpages for either).
When does rebase/rebaseall fail with an error=6?
Thanks,
Linda
