CVS libstdc++-v3 encounters make assertion

[Benjamin Kosnik]

Hello all. Apologies if this is a known bug, but I did not find a
reference to it anywhere in the archives. (I did see some posts from
Mumit with patches that are now in the libstdc++-v3 tree.)

Using the Cygwin release one CD, I checked out the CVS sources to v-3
and tried to do a configure/make. Everything goes pretty smoothly,
then I get an error in make, as follows:

Hmmm. Is this a known problem?
