Could not reproduce this bug on RH Enterprise Linux 4 / GCC 4.1.2.

[Martin Sebor]

Setting a process-wide locale by means of the LANG and LC_XXX environment variables is the primary means for localizing an internationalized program. Bumped up Severity to Critical.
Added 4.1.4 and 4.2.0 to the list of Affected Versions.
Disabled formatting in Description.
Set initial time estimate.

Corrected a typo (missing space) in Summary.

Readily reproducible on Fedora 8:

  && ../bin/localedef -w -f ~/stdcxx/etc/nls/charmaps/ISO-8859-1 -i ~/stdcxx/etc/nls/src/de_DE de_DE.ISO-8859 \
  && make t && env LC_ALL=./de_DE.ISO-8859 ./t
