  Thanks for the hint. Thats the reason:

  configure:2203: checking for socklen_t in <sys/socket.h>
  configure:2214: gcc -c -D__EMX__ -DOS2 -Zmtd -D__ST_MT_ERRNO__ -O2 -W -Wall
  -Wcast-align -Wcast-qual -Wmissing-declarations -Wmissing-prototypes
  -Wpointer-arith -Wreturn-type -Wstrict-prototypes -pedantic -D_GNU_SOURCE
  conftest.c 1>&5
  configure:2209: warning: function declaration isn't a prototype
  configure: In function `main':
  configure:2210: `socklen_t' undeclared (first use in this function)
  configure:2210: (Each undeclared identifier is reported only once
  configure:2210: for each function it appears in.)
  configure:2210: parse error before `len'
  configure: failed program was:
  #line 2205 "configure"
  #include "confdefs.h"

  #include <sys/socket.h>

  int main() {
  socklen_t len
  ; return 0; }

  include/sane/config.h contains
  #define socklen_t int
  but seems that this #define is not available at 'configure-time'
  How should this be fixed?

  Franz
