I got the error listed above while configuring
(./configure --prevfix=...) on soloris 2.6 (SunOS pitt31 5.6 Generic_105181-33
sun4u sparc SUNW,Ultra-Enterprise).

This happened in both version 1.0.12
and 1.0.13 of the Common C++ gnu library.  The project pages says
that the latest stable is 1.9.6, but the links to the source download  end
at version 1.0.13.

both version that I tried to compile
get the following error when making after a configure with the above error:
