Please, a word of help (Was: Re: egcs 1.1.1: apparently multiple library inclusion??)

Last week on the egcs list I myself wrote:

No responses, sorry if my question was obscure... or just a
FAQ?  Because if it is a FAQ, I certainly didn't find in the
egcs.cygnus.com FAQ.

I'm ready to do any testing or reinstalling or whatever, I've
already installed this three times, with another person doing
an independent install on a different machine, but always the
same results.  I'm getting desperate, I don't want to rewrite
all those things that were so easy to write using the STLs.

My feeling is that is I could manage to get these obscure errors
every time, someone must have come across them before...

Anyone?
