While I was trying to implement strptime, I have noticed that strftime does not
support the 'E' and 'O' conversion modifiers of the conversion specifiers.  If
the locale is "C" the modifiers shall be ignored.  Because djgpp only supports
"C" locale, both will simply be ignored.

Objections?  Wording in documentation OK?

Regards,
Juan M. Guerrero
