Support for "namespace" keyword in Watcom?

I have downloaded the OpenEXR C++ libraries and I am
trying to compile them with the OpenWatcom 1.9 complier
which the website says is the latest version. It chokes on
the keyword "namespace" and I am wondering if this part
of C++ is supported or not.

Thanks.

Yes, there is some namespace support in OW 1.9. Which OpenEXR download and
which file were you having trouble with?

I have downloaded the lastest OpenEXR 2.2.0 releases
from this URL:

http://openexr.com/downloads.html

As a start, I am using the viewer code since it must contain the
code needed to read a file and interpret its contents and format:

http://download.savannah.nongnu.org/releases/openexr/openexr_viewers-2.2.0.tar.gz

Figuring this code uses the base library code in the base
package I am also using files from this package:

http://download.savannah.nongnu.org/releases/openexr/openexr-2.2.0.tar.gz

There are headers in <config> and <config.windows> directories of
the openexr-2.2.0 package. Since I am running on Windows-7
I am selecting the file from <config.windows> when there are two of
them assuming that this one is altered to work with the OS I am using.

I am trying to compile the file "FileReadingThread.cpp" and I have been
fetching header files and including them in the local directory to resolve
"file not found" errors and modifying the include string encapsulators
to make the compiler look in the current directory where they occur.
Below is a listing of the output I get when trying to compile the source
file:
