I have some hints that could fix the problem, but I can not test

Dear Bernard,
please let me know if I can help (e.g., by giving you access to
a machine with gcc 3.4.1).

The template code for Normalrref is never instantiated, that's why the
error does not appear with previous versions of gcc. Declaring
temp and newcoord as vector< monomial<T> > should fix the compilation 
error.
OK.
...
zero is assumed to be declared of type T when these functions are
instantiated. I don't know how to declare zero as a template variable
(would extern T zero; work inside a function?)
Yes, if this is what you want.  However, this conflicts
with the declaration
extern gen zero;
in gen.h.
...
gcc is correct, f. should be removed (twice)
OK.
We still have the following problems (apart from the conflicting
declarations for zero):
c++ -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -g -O2 -c gausspol.cc  -fPIC -DPIC -o .libs/gausspol.lo
gausspol.cc: In function `bool giac::gcd_modular_algo(giac::polynome&, giac::polynome&, giac::polynome&)':
gausspol.cc:982: error: no match for call to `(giac::polynome) (giac::polynome&, giac::polynome&, giac::gen&)'
poly.h:385: note: candidates are: giac::tensor<T> giac::tensor<T>::operator()(const T&) const [with T = giac::gen]
poly.h:266: note:                 T& giac::tensor<T>::operator()(const giac::index_m&) [with T = giac::gen]
poly.h:277: note:                 const T& giac::tensor<T>::operator()(const giac::index_m&) const [with T = giac::gen]
The following is cured by adding an include of <iostream> in global.h
c++ -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -g -O2 -c ti89.cc  -fPIC -DPIC -o .libs/ti89.lo

global.h:130: error: `cout' is not a member of `std'
A similar problem with cerr is in monomial.h.
The nastier seems to be this one:
monomial.h: In function `std::vector<giac::monomial<T>, std::allocator<giac::monomial<T> > > giac::operator+(const std::vector<giac::monomial<T>, std::allocator<giac::monomial<T> > >&, const std::vector<giac::monomial<T>, std::allocator<giac::monomial<T> > >&)':

I attach the patch file containing my changes up to now.
I would be grateful if you could tell me how to procees.
All the best,
