I am trying to build the octavecvs by gcc 4.2.1 on Cygwin

[Tatsuro MATSUOKA]

I am trying to build the octavecvs by gcc 4.2.1 on Cygwin
expecting better optimizing ability of gcc 4 than gcc 3.
Progblem with gfortran was solved using newest version
ATLAS by gcc 4.2.1 on Cygwin.

In making process, the following error was appeared.

*******************************************

with make -i liboctave and libcruft were succesfully
build.  Perhaps this error will be overcome, the build
will be successful.  Please help me.  

Sincerely.
