Hi.

I've been running Chromium tests under wine under Valgrind (see
http://wiki.winehq.org/Wine_and_Valgrind ) and found an incorrect
implementation of lstrlen in Wine.

According to MSDN, lstrlen should return 0 if the argument is NULL
See http://msdn.microsoft.com/en-us/library/ms647492(VS.85).aspx

In include/winbase.h I found this:
>>>>>>>>>
extern inline INT WINAPI lstrlenW( LPCWSTR str )
{
    const WCHAR *s = str; 
    while (*s) s++; 
    return s - str; 
}

extern inline INT WINAPI lstrlenA( LPCSTR str )
{
    return strlen( str );
}
<<<<<<<<<
Both implementations handle the "str=NULL" case incorrectly.
strlen segfaults on Linux if you simply call strlen(NULL).
