Then this is what you should do. :)

Autoconf tries to allow for absolute paths that contain spaces and other
shell metacharacters, as long as the build tree itself does not add any
further; but it may not always succeed (patches welcome).  But even if
autoconf is perfect in its use of quoting, many other packages write
configure.ac that are not as careful.  In this regards, I suspect that
it is the SystemC code at fault for not handling metacharacters in the
absolute path.  In fact, it may be an unfixable problem; the 'make'
language is very unforgiving in its syntax (it lacks double quotes that
shell has), and any project that uses automake in addition to autoconf
to generate the configure/Makefile pairs may result in a generated
Makefile that cannot deal with absolute paths that aren't sane.

So unless you can point to a specific error message, and prove that it
comes from autoconf proper and not from SystemC's configure.ac file, I'm
inclined to think this is not an autoconf bug, but a normal limitation
that you'll just have to work around via symlink or mount point.
