after having sucessfully worked with rpm-2.5.2 under solaris I tried to
build rpm-3.0.3. For now, the problems are related to misc/err.c.
The configure script find out correctly that solaris 2.6 hasn't an err()
function in the system libraries and tries to build it. This fails because
of a lacking features.h that is included by err.c.
After installing a trivial features.h the make process runs until trying to
link dump. This has an unresolved err symbol. This in turn is in
misc/libmisc.a, which is not linked with.
When linking dump manually with libmisc.a, it fails with unresolved symbols
in err.o such as __progname, __set_errno and fputs_unlocked.
Looks like a linux/glibc-ism.
