    I can'remember in wgich backend it fails, but it does so in several of
    them. I don't think it's a good idea to have the same constant #defined
    in many files (it's currently defined in 8 c files in backend).

    I'm using autoconf and then running configure (though I edit it to
    compile with debug info).

    For instance, nec.h contains

    typedef enum
        /* PCIN500, PCINXXX are used as array indices, so the corresponding
           numbers should start at 0
        unknown = -1,

    and sharp.h contains

    typedef enum
        /* JX250, JX330, JX350, JX610 are used as array indices, so the
           corresponding numbers should start at 0
        unknown = -1,

    However, nec.c contains the string "JX" 17 times, mostly in comments,
    but otherwise:

      /* The JX330, but nut not the JX250 supports auto selection of
    ADF/FSU: */
      if (s->dev->info.adf_fsu_installed && (s->dev->sensedat.model ==
        s->dev->info->scansources[i++] = use_auto;


    #ifdef NOTUSE_PCIN500
      if (s->dev->sensedat.model != JX610)

    Do all those platforms support System V APIs?

    configure --sysconfdir=. --program-suffix=.exe --disable-dynamic


    CFLAGS = -g -O0 -m486 -Zmt -W -Wall -Wstrict-prototypes -Wreturn-type
    -Wcast-align -Wpointer-arith -Wcast-qual -ansi -pedantic
    (in libs/Makefile)


    configure --sysconfdir=. --program-suffix=.exe --disable-dynamic
    --without-x --disable-warnings


    CFLAGS = -g -O0 -m486 -Zmt -W -Wall -DSCSIBUFFERSIZE=131072

    i.e., if I don't explicitly use --disable-warnings, then the WARN_CFLAGS
    variable gets used (line 1547 of my configure), rather than

    > What do you mean by "structure parameter"?

    param is the name of the structure.

    Things seem to be going better than I feared. I managed to run a scan
    (full colour) with the exe that I compiled.

    FWIW I haven't had too much problems compiling older version on Linux
    and FreeBSD (though for the latter, I've not managed to get the driver
    to recognise the SCSI host card, ditto for Solaris 7).

    A bientot
