I'm just guessing, since I don't have much experience with borland compilers.
It definitely seems as a compiler related problem. 
Problem can be related to way the function detail::trim_begin is called.

I'm using relative access convetion. So I use detail::trim_begin(...).
In some places it helped if the namespace was specified explicitly.

So I can try to make a fix in the cvs, but I will need somebody to test it.

Can you arrange it?
