15:41 Bug #118: unistd and call to access in Main.C
- Discovering that BOOST seems to offer a ready-made solution, and that @access@ is old-style C-library.
-
- Replace call to @access@ in Main.C (about line 192) by calls to BOOST filesystem fns such as @exists@ and @is_regular...
-
- As far as I can tell BOOST does not offer such a simple fn.
-
- To enable compilation on MSVC, I had to add defn of @isblank@.
Currently there are 3 separate (but identical) defns ...
