I can confirm this patch resolves the test case on MacOS X with gcc 4.1
branch...

Before patch...

The following file will take roughly 10 minutes to compile

After patch...

Tue Mar 28 23:26:00 EST 2006
The following file will take roughly 10 minutes to compile

This is on a dual 2.0GHz G5 with 2 Gb of RAM. However I don't see any
significant impact
on the compile time for the aermod polyhedron benchmark.
