[PURRS-devel] Cannot compile GIAC 0.4.0

[Roberto Bagnara]

Dear Bernard,

I have downloaded GIAC 0.4.0 and tried to compile it with
GCC 3.4.1 (which contains a fix for the bug I told you back
in May).  However, the compilation fails immediately as
follows:

cd /usr/local/distrib/giac-0.4.0/
make
make  all-recursive

The compiler seems right in, e.g., `temp' is undeclared in
giac::Normalrref().  Have you got any idea what the problem
may be?
All the best,

     Roberto
