[Nel] VC6 Build Error C1001

[Paul Siegel]

Hmm, I was compiling NeL just fine a couple days ago.  Today I decided to
re-get all the code from CVS and clean and rebuild the whole project.  Under
any configuration, it starts compiling the misc project, and gets as far as
bsphere.cpp when I suddenly start getting these errors:

bsphere.cpp
fatal error C1001: INTERNAL COMPILER ERROR
        (compiler file 'msc1.cpp', line 1794)
         Please choose the Technical Support command on the Visual C++
         Help menu, or open the Technical Support help file for more
information
geom_ext.cpp
fatal error C1001: INTERNAL COMPILER ERROR
        (compiler file 'msc1.cpp', line 1794)
         Please choose the Technical Support command on the Visual C++
         Help menu, or open the Technical Support help file for more

line.cpp
fatal error C1001: INTERNAL COMPILER ERROR
        (compiler file 'msc1.cpp', line 1794)
         Please choose the Technical Support command on the Visual C++
         Help menu, or open the Technical Support help file for more

You get the idea, it gives this error for every file left in the project.
I'm running VC6 sp5.  Anyone got any idea why this would happen?
