build and installation

[Timothy Ritchey]

I recently downloaded the 2.90.1 snapshot of the v3 stdc++ library, and
attempted to install it using the latest (19981019) egcs snapshot. I
fixed a few build problems with string/locfacet, and got it built, and I
thought installed, however, none of the headers seem to have moved into
their respective locations, and I am at a complete loss for how to
figure out what goes where. Is there any documentation on
building/installing the library that I have not found? A need for a
reasonably complete valarray implementation is what made me look at the
library, but no luck yet.

Cheers,
