Greetings Martin.
For what it's worth, this isn't a problem restricted to XLC++. My
reading of the .config files indicates that the only compilers that
won't be affected are the osf_cxx, Sunpro, reliant_cds, como and eccp
compilers. The first two compilers don't use a comma in the rpath
option, and the remainder don't have an rpath switch defined.
It might be possible to alter the makefiles to mangle the path, escaping
the comma, but I suspect that could cause other problems. I would
hazard a guess that spaces in the value of $BUILDDIR might also cause a
number of problems.

I've run into a linker error when building with IBM XLC++
in a directory whose name contains a comma (see below).
The problem is that we're passing the absolute pathname
of $BUILDDIR/lib to the linker via the -Wl compiler driver
option. This option uses the comma to separate individual
arguments from one another. I don't know if it's worth
trying to deal with this or not but I thought I'd mention
it in case someone else runs into the same problem or in
case Andrew has an idea for how to fix it.
