compilation error

during compilation of sane-1.0.1 with
gcc-2.95.2
glib-1.2.6
gtk+-1.2.6
gimp-1.1.14

I got

xscanimage.c:79: conflicting types for `GIMP_EXTENSION'
/usr/local/include/libgimp/gimpenums.h:289: previous declaration of `GIMP_EXTENSION'

file:gimpenums.h

typedef enum
{
  GIMP_INTERNAL,
  GIMP_PLUGIN,
  GIMP_EXTENSION,
  GIMP_TEMPORARY
} GimpPDBProcType;

file:xscanimage.c

enum
  {
    STANDALONE, GIMP_EXTENSION
  };

I replaced GIMP_EXTENSION with GIMP_EXTENSION2 in xscanimage.c.

(x)scanimage are crashing at startup

Starting program: /usr/local/bin/xscanimage

Program received signal SIGSEGV, Segmentation fault.

It happens with my SCSI scanner if I forgot to set the permissions of (x)scanimage with chmod.
Looks like a return code is ignored somewhere in sane.

using batch option of scanimage

- scanimage executable exit now with sane status, the status SANE_STATUS_EOF is mapped to SANE_STATUS_GOOD.

- I added a new batch option

scanimage --batch[=pathname]
scanimage -b[=pathname]


the default for pathname is "out%d.pnm" where %d is replaced with 1, 2, ... . If you don't know what %d means type "man printf".

Notes

- take care that the resulting pathname is not longer than 1023 characters.

- if scanimage fails or is running out of documents to scan (means anytime you use the --batch option) it produce an empty file at the very end.

- It will overwrite existing files.
