From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050403 Firefox/1.0.2 Description of problem: rpm -q -p ./compat-gcc-32-c++-3.2.3-47.fc4.i386.rpm -l shows, among other useful files: - /usr/include/c++/3.3.4/ and all expected stl includes in that directory - /usr/lib/gcc-lib/i386-redhat-linux/3.3.4/libstdc++.a - /usr/lib/gcc-lib/i386-redhat-linux/3.3.4/libstdc++.so - /usr/lib/gcc-lib/i386-redhat-linux/3.3.4/libsupc++.a I found this trying to install compat-gcc-32-c++ alongside of compat-gcc (the 3.3.4 compiler) on FC3 release. I know that this is non-standard, but I don't think the 3.3.4 files listed above should be part of the 3.2.3 RPM.

That is intentional. GCC 3.2.x and 3.3.x is (moreless) binary compatible, but there is just backward compatibility in libstdc++, so 3.2.x built code can work against 3.3.x libstdc++ but not the other way around. GCC 3.2.3-RH has been chosen for compatibility compiler because unlike 3.3.x Red Hat needs to support 3.2.3-RH for a few more years and with the included 3.3.x libstdc++ you can run both 3.2 and 3.3 compiled programs against it.
