I have compiled sane-backends-2009-03-02 with gcc-4.3.3 .

I have now changed tools/sane-config.in as follows:

line 15:
Change @DL_LIB@ to @DL_LIBS@ .

line 89 and line 91:
Remove @GPHOTO2_LDFLAGS@ .

NO change in 'acinclude.m4'.

Now '/usr/bin/sane-config' contains:

LIBS=" -ldl"


As xsane needs SANE_CAP_ALWAYS_SETTABLE in xsane-0.996/src/xsane-back-gtk.c,
I had changed:

--- include/sane/sane.h.orig	2009-03-01 20:41:13.000000000 +0100
+++ include/sane/sane.h	2009-03-01 20:41:41.000000000 +0100

I found the value in sane-backends-1.0.19/include/sane/sane.h in line 111.
And I found the value in sane-backends-1.0.9/include/sane/sane.h in line 103.

Are all these versions _not_ part of the stable API ?

By the way, compiling sane-backends-2009-03-02 gcc-4.3.3 warned several times:

passing argument 1 of 'free' discards qualifiers from pointer target type

Visiting the reported lines I found that the

SANE_Device.{name,vender,model}

were freed although they are 'SANE_String_Const'. Is it correct to free 
constants? A list of files is shown below.
