    Problem Text
    Page 105 of the XPG5 XSH spec satates the prototype for btowc() is
    the following:

    wint_t btowc(int c) ;

    and further states:

    " The btowc() functions returns WEOF if c has the value EOF or if (unsigned
    char) c does not constitute a valid (one-byte) character in the initial
    shift state."

    The code for the btowc call look like this:

    rwchar = btowc((int) w_cfg.mbcurmax1);

    mbcurmax1 is defined to be an unsigned char * in SRC/INC/wchar_cfg.h.

    Thus a pointer to char is being converted to int instead of the contents
    at that address location. The above line should be changed to the following

    rwchar = btowc((int) *w_cfg.mbcurmax1);


    Test Output
    ************************************************************************
    /tset/MSE.os/wchar/btowc/T.btowc 3 Failed

    Test Description:
    When c does not represent a valid character in the initial shift
    state, then a call to btowc(c) returns WEOF.

    Test Strategy:
    OBTAIN structure of multibyte strings using wcharcfg()
    IF the character string mbcurmax1 is not empty string
    CHANGE to wide character locale using setlocale()
    CALL btowc((int)mbcurmax1)
    VERIFY that btowc() returned WEOF

    Test Information:
    btowc() with invalid character did not return expected WEOF
