I am. Up to now, I have a dual cygwin installation 1.5/1.7 because I
was unable to use boost nor wxwidgets with 1.7.
I recently decided to make another effort to build boost with 1.7
because I feel that it will be difficult to maintain my build chain
based on cygwin 1.5.

I realized that there are 2 mingw32 compilers coming with cygwin 1.7:
i686-w64-mingw32 and i686-pc-mingw32.
I imagine that they correspond to:
- w64 ->http://mingw-w64.sourceforge.net/
- pc -> http://mingw.org/

I first tried to use the -w64- version with which I have troubles
building boost.
However, good news: I just finished building boost with the -pc-
version! I still have to build wxwidgets (currently running).

It would be nice to understand why the -w64- version does not work but
it seems to be beyond my competencies.

This is an old version (1.43). I want to use the latest one (1.47)
