libstdc++ on RedHat

[Alex Seriy]

I just downloaded Xalan 1.4 and Xerces 2.1 (xerces-c2_1_0-linux7.2gcc31) 
binaries. I have RH7.2 and RH8 mixed environment. I looks like Xerces 
need libdstdc++.so.4 that is not present on either distributions of 
RedHat. RH8 comes with libstdc++.so.5 which is part of libstc++ RPM. I 
searched through official releases and updates for 7.2 through 8.0, and 
also rawhide. I don't seem to find the runtime library. Did anyone have 
this problem? Any help will be greatly appriciated.
