Mark Brown commented on STDCXX-333:
-----------------------------------
I tried to see if I could reproduce this problem on Cygwin. My version of
Cygwin doesn't have any locales so I tried to generate the en_US.UTF-8 locale
using the stdcxx localedef program. I got this error:
nls$ ../bin/localedef -c -f /home/mbrown/stdcxx/etc/nls/charmaps/UTF-8 -i
/home/mbrown/stdcxx/etc/nls/src/en_US en_US.UTF-8
call to system LC_ALL=C /usr/bin/locale -a >/tmp/tdf4.0 2>/dev/null: No such
file or directory
