pwlib compilation error

[Frank Solensky <frank solensky org>]

Garnome 2.15.2.1
While building pwlib to satisfy dependencies from opal and ekiga, I ran
into the following:

---------------
make[7]: Entering directory `/home/fsolensky/gnome/garnome-2.15.2.1/bootstrap/pwlib/work/main.d/pwlib-1.10.0/plugins/vidinput_v4l'

---------------

The problem seems to be a result of the first "-I" option: the file
garnome/include/ptlib/vidio.h has a two-argument version of the macro.
The file main.d/pwlib-1.10.0/include/ptlib/vidio.h -- the intended
reference -- has only one.

My question is on how to proceed: cd to the directory and compile the
files that reference the macro manually?  Modify some Makefile or
environment variable to get the first "-I" out of the way?  Something
else?

Thanks again in advance..
