Exactly. Fixed in CVS. The easy fix was to add BOOST_FILESYSTEM_DECL for the 
two functions, in both the header and implementation files.

I'm adding two dll tests to detect regressions. The two added dll tests are 
working fine for Intel, Metrowerks, and Microsoft compilers, but are getting 
runtime failures for Borland and GCC. I'll try to figure out what is 
happening and get a fix together.

Thanks for the bug report,
