Hi,
I have a program that needs the locale support, so I include 'locale.h'. 
I make the program but the output was wrong.
With the cygwin library the setlocale function do not work, but if I 
link with mingw library it is ok I am sending a sample program that 
demonstrate the error.

Linking with CYGWIN:
    marcelo AT est01 /usr/src/testes/locale/msdn
    $ gcc -o crt_locale crt_locale.c    
    marcelo AT est01 /usr/src/testes/locale/msdn
    $
    $ ./crt_locale.exe
    In German locale, strftime returns 'x'
    No Brasil locale, strftime retorna 'x'
    In 'C' locale, strftime returns 'x'
    marcelo AT est01 /usr/src/testes/locale/msdn
    $

Linking with MINGW (-mno-cygwin)
    marcelo AT est01 /usr/src/testes/locale/msdn
    $ gcc -mno-cygwin -o crt_locale crt_locale.c
    marcelo AT est01 /usr/src/testes/locale/msdn
    $
    $ ./crt_locale.exe
    In German locale, strftime returns 'Sonntag, 07. Dezember 2003'
    No Brasil locale, strftime retorna 'domingo, 07 de dezembro de 2003'
    In 'C' locale, strftime returns 'Sunday, December 07, 2003'
    marcelo AT est01 /usr/src/testes/locale/msdn
    $

Thanks,
Marcelo Modolo
