Hi,

I was just about to build the filesystem library for the first time on my
Win98+BCC 5.5.1 environment, but I got lots of errors from
"type_traits/is_convertible.hpp"
Since the regression_test shows that this library passed bcc5.6.1 yesterday,
I thought that is_convertible might have changed today. Indeed, version 1.10
(the previous)  works fine. (that is, I was able to build the FS library)

I attach here the compiler output using the -Q compiler option (which shows
extended error information).
