Unfortunately the complete input is rather huge.  I'll try to pare it down. 
Does all of this stuff spit out by the compiler (below) provide any clues?  Does
anyone have any idea exactly what this output means?

The compiler is running on a Pentium II.  If you look at the command line,
you'll notice that I don't explicitly set the architecture for which I'm
compiling:

eg_g++ -g -c -Wall -ansi -pedantic -D_DEBUG -I.
-I/usr/local/libmrc/include -I../../common -Itransforms -D_GNU_SOURCE
-D_REENTRANT -DPLATFORM_LINUX=1 -DEXPORT= -fno-implicit-templates
-fnew-exceptions -fasynchronous-exceptions -fvtable-thunks -fexceptions
TransformConnectionComponent.cpp -o TransformConnectionComponent.otd

Am I getting i686 or i586 (or i486?) if I compiled egcs using its default
compilation rules on a Pentium II machine?

For the record, I get the error both with and without -g, and with and without
-O2.
