'cd hg5-1.6.8', './configure', 'make' runs with no errors
on a clean install of Suse 11.0,
using gcc43-4.3.1_20080507-6.1 .
There is a 'compat-libstdc++' for Suse 11.0, but it isn't
used, as all code in HG5 is c-code, no c++.
And there is no compiler connected to 'compat-libstdc++'.
There is no gcc-3 for Suse 11.0, unless you installed an
alternative one yourself.
I do not see, how you can talk about a gcc3, gcc4 conflict,
unless you are using some special configure options.
The only possible reason for an error I can think of, is if
you have another version of gcc-4.3 .? ?
