Your error message indicates that exceptions are disabled.  Try not
disabling them.  I think some versions of GCC might disable exceptions by
default based on the language its compiling for -- e.g., if it's invoked as
'gcc' or the filename extension designates a C file.  I didn't see this
behaviour under Cygwin, though.

I can get it to compile under Cygwin just by adding the Boost include with
-I and defining __linux__ with -D.
