changeset 21874 makes trunk uncompilable

[Uwe Stöhr]

Hello Abdel,

in http://www.lyx.org/trac/changeset/21874
you changed
- unsigned long sum(FileName const & file)
+ unsigned long sum(char const * file)
But this leads to this compilation error:

D:\LyXSVN\lyx-devel\src\support\lyxsum.cpp(140) : error C2228: Left from ".isDirectory" must be a 
class/structure/union.
Type is 'const char *'

regards Uwe
