Subject: atlas3: FTBFS with gcc-4.0 [amd64]

Package: atlas3
Severity: normal
Version: 3.6.0-19

When I try to build atlas3 with the default gcc set to gcc-4.0, I get:

...
ATLAS has detected that you are running on an x86 architecture
(eg., Athlon, P4, PIII, etc), but do not have a pre-2.96 gcc installed.
Using gcc 3/2.96 will result in a performance loss of 10-20% IN THE BEST CASE
over a gcc previous to 2.96. If your install goes slightly wrong, performance
drops of 50% are more normal with these compilers. Full details of this
problem can be found at:
   http://www.cs.utk.edu/~rwhaley/ATLAS/gcc30.html
In the meantime, we suggest you abondon this ATLAS install, and install a gcc
that delivers decent x86 performance, and restart the install then. You
do not need to be root to install, and full instructions, along with all
needed files, are given in the ATLAS errata file at:
   http://math-atlas.sourceforge.net/errata.html#UnixGccInst

   Stop ATLAS install? [y]: couldn't execute "kill": no such file or directory
    while executing
"exec kill -TERM $i"
    invoked from within
"expect -re "ready to continue?" {send "\n" ; exp_continue} \
        "Enter number at top left of screen" {send "\n" ; exp_continue} \
        "ENTER TO CONTINUE" {..."
    (file "debian/config.expect" line 6)
make: *** [bin/Linux_base_static/Make.inc] Error 1

It seems config.c doesn't know about gcc 4.0; changing line 697 of
config.c to accept the case (major >= 4) as well, the package then
compiles fine until it runs into compiler errors in uumtst.c. (This
will probably affect i386 as well.)
