The package adds -prefer-non-pic to the CFLAGS unconditionally (does
not depend on the target arch) and relies on libtool to determine if
it should pass -fPIC or not. As far as I know this works OK on all
arches except hppa. The configure workaround I posted compiles a dummy
library with -prefer-non-pic and checks if it fails.

The way its done in the package is that the was doing
I replaced it with
with AC_LIBTOOL_NON_PIC as quoted in the previous email.

That package (using -prefer-non-pic unconditionally) is into debian
now, it's been compiled successfully on all debian-supported arches
except hppa, so that would be x86, m68k, sparc, alpha, powerpc, arm,
mips/mipsel, ia64 and s390. I'm not sure exactly which of these use
-fPIC or not. Only hppa breaks, as it tries to not use -fPIC where the
architecture apparently requires -fPIC.

Hope this helps,

Is this the best that god can do ? Then I'm not impressed.
