the Fedora specific compilation flags for 32 bit arch is

=2DO2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=3D2 -fexceptions -fstack-protect=
or
=2D-param=3Dssp-buffer-size=3D4 -m32 -march=3Di386 -mtune=3Dgeneric
=2Dfasynchronous-unwind-tables

I guess for x86_64 arch it should be=20

=2DO2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=3D2 -fexceptions -fstack-protect=
or
 --param=3Dssp-buffer-size=3D4 -m64 -mtune=3Dgeneric

for more details on your arch:
$ rpm --showrc | grep flags=20
and pay attention to :
 * optflags
 * global_cflags

Like I said before, I'm open for any improvement of the ngspice package=20
especially for the x86_64 arch since, I don't have the specific arch to tes=
t=20
it, not even at my university. :(
