Yes.  Actually it is not so uncommon to have spaces as a part of a
volume name (e.g., /Volumes/Macintosh HD/Applications/Xcode.app/...).
That's why I didn't apply the patch in
http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00760.html to
the Mac port.

I'd encourage those who build Emacs themselves to install the Command
Line Developer Tools on Mavericks (i.e., $ xcode-select --install) so
they have /usr/include directory, which does not exist by default.
But an alternative idea might be to try xcsdkdir only if it does not
contain *, ?, [, or blanks.
