Hi Thomas,

why bother about setlocale since strerror should give something anyway?
Then I do not tend to produce unknown errors 8-), but to be sure it's
easy
to print errno also as a number! Including errno.h and using errno and
strerror worked for me on every real Unix variant I had to deal with,
also under NT with Cygwin (of course), but Interix and UWIN as well.

Bye, Heribert (heribert_dahms@icon-gmbh.de)
