two fixes for MacOS X

[<ivt...@li...>]

Patch:    ivtools-021116-johnston-075
For:      ivtools-1.0.6
Author:   joh...@us...
Subject:  two fixes for MacOS X
Requires:

This is an intermediate patch to ivtools-1.0.6.  To apply, cd to the
top-level directory of the ivtools source tree (the directory with src
and config subdirs), and apply like this:

         patch -p0 <ThisFile

Summary of Changes:

- disable use of X11 shared memory extension for MacOS X.  This may
only be a problem with 10.1, or only be a problem with XFree86 4.2, so
it may be reinstated in the future.

- customize iostream include files for MacOS X Jaguar (10.2), to mask
the difference between Apple's version of gcc-3.1 libstdc++ and
everyone elses.  This is untested, so let me know if it worked for you.
