Input stream crash with gcc 3.1/cygwin (stack trace incl.)

[Benjamin Kosnik]

Okay. This has been an ongoing issue for a bit. David and I tried to 
tackle this on the libstdc++ list, on and off last month. I don't have 
full-time access to a cygwin setup, and so it's kind of hard for me to 
debug this. 

However.

Your email had a pretty good backtrace, and I went through the CVS logs 
for the cygwin files, and cross checked this with David's postings on 
gcc-testresults. It looks like my 2002-01-20 patch killed ctype support 
for this platform.

Can you please try this:
