   4 Subject: [PATCH] sane_backend: add missing config.h
   5
   6 We should include config.h from sanei_backend.h in order to use the
   7 correct if/else HAVE_FOO.
   8
   9 For some reason with Glibc or uClibc there is no problem but with musl
  10 we have the following weird issue:
  11
  12 In file included from epsonds.h:41:0,
  13                  from epsonds-jpeg.c:18:
  14 ../include/sane/sanei_backend.h:99:33: error: expected ';', identifier or '(' before 'int'
  15  # define sigset_t               int
  16                                  ^
  17 ../include/sane/sanei_backend.h:99:33: warning: useless type name in empty declaration
  18
  19 That's because HAVE_SIGPROCMASK is not defined although it's correctly
  20 detected by the configure script.
  21
  22 $ grep config.log
  23 config.log:#define HAVE_SIGPROCMASK 1
  24
  25 So, include config.h to avoid to redefine sigset_t.
