Can you test a possible fix since you have access?  They appear to be
using an unsigned pointer so traditional "-1" can't be used.  In
sanei_thread.c, modify these three blocks:

#ifdef WIN32
        pid->p = 0;

[...]

#ifdef WIN32
        if (pid.p == 0)
            rc = SANE_TRUE;

[PATCH] scanbd: Makefile-001 ensure target dirs exist

Hi,

I am packaging scanbd for Fedora (someone stop me if it's done) and I
came across two things I would like to add to the Makefile:

1) 'make install' should not assume all its target dirs exist (it
   doesn't for two of the three dirs it targets but it assumes
   /etc/dbus-1/system.d exists)

and

2) 'make install' should respect $PREFIX and / or $DESTDIR if set,
   DESTDIR being the conventional one RPM will set when doing mock
   builds / installs for various purposes during the RPM packaging
   process.

Would you please consider these two patches and let me know if they
are acceptable or if I can improve them to make them so?  The patches
were created by 'svn diff' against SVN trunk (checked out a few
minutes ago).

The first patch follows and the second will be set as a reply (with
changed subject) to this mail.

Thanks,
Martin

Close. The attached patch fixes the compile issue and the resulting DLL 
works for me and my scanner on 7 64-bit.

German translations

Hi,

I am adding German translations for the new Pixma options to the German 
translation file:

#: ../backend/genesys.c:5957 ../backend/pixma_sane_options.c:293
#, no-c-format
msgid "Threshold curve"
msgstr "Schwellwertkurve"

#: ../backend/genesys.c:5958 ../backend/pixma_sane_options.c:294
#, no-c-format
msgid "Dynamic threshold curve, from light to dark, normally 50-65"
msgstr ""
"Dynamische Schwellwertkurve, von hell zu dunkel, nomalerweise 50-65"

#: ../backend/pixma_sane_options.c:143
#, no-c-format
msgid "Gamma function exponent"
msgstr "Gamma-Exponent"

#: ../backend/pixma_sane_options.c:144
#, no-c-format
msgid "Changes intensity of midtones"
msgstr "Verändert die Intensität der mittleren Farbtöne"

For other scanners there are many German translations missing. I need 
your help to add them, too.
Please add / correct the German translations below:

Re: [PATCH] scanbd: Makefile-001 ensure target dirs exist

Hi Martin,

thank you for the patches.
They are merged to trunk and into release/1.2.
Also make a file release scanbd-1.2.tgz on SF.

Thanks,

Wilhelm
