Thanks for this informations.

Now fixed in CVS.

This one was already fixed in CVS.

Changed in CVS now.

sane-devel is usually the right place for such discussions/proposals
if the patch/change doesn't get too long.

Currently, README.hp-ux states:

| Under HP-UX, it is necessary to add options -Aa and -D_HPUX_SOURCE to
| the compiler flags when using HP's C compiler (not gcc).  This can be
| done by invoking configure with:
|
| CC=cc CPPFLAGS=-D_HPUX_SOURCE CFLAGS=-Aa ./configure

Sorry for my cluelessness: Is -D_HPUX_SOURCE necessary, or does it
harm in your case? What's the difference between -Aa and -Ae? Maybe
you can rewrite the README.hp-ux for us?

Thanks. Oliver, can you put this on www.mostang.com?
