ugh. Well, I had to get some of this stuf in. 

Non-glibc targets are broken in CVS at the moment. I'll have a fix for
that in a moment, or I'll back out my change.

basically, you need to put the libstdc++ directory into what you are using
for egcs, so that libioP.h can be found in the libio source directory.

<bkoz@decepticon.cygnus.com> {/horton/bkoz/src.egcs}
% ll -d libs*
lrwxrwxrwx   1 bkoz     cygnus         12 Feb  9 12:33 libstdc++ ->
libstdc++-v2/
drwxrws---   8 bkoz     cygnus       4096 Feb  9 11:09 libstdc++-v2/
drwxrws---  16 bkoz     cygnus       4096 Feb  9 11:10 libstdc++-v3/

and do the soft link according to what you want to build.

I am having some problems with bits/valarray_array.h
