<P>Looks like emx fails when it encounters a #warning. I don't think we

can fix this easily at least I don't have an idea.

|

<P>conftest.c is the file generated by configure. Look for the lines:
|
|
<BR>
|
|
<P> cat > conftest.$ac_ext <<EOF
|
|
<BR>
|
|
#line 1621 "configure"
|
|
<BR>
|
|
#include "confdefs.h"
|
|
<BR>
|
|
#include <$ac_hdr>
|
|
<BR>
|
|
EOF
|
|
<BR>
|
|
<P>in configure. That means put everything in the lines after the "cat"
|
|
<BR>
|
|
not including the "EOF" into conftest.c. $ac_hdr is substituted by
|
|
<BR>
|
|
sys/socket.h in this case. confdefs.h contains things like the package
|
|
<BR>
|
|
name and other defines.
|
|
<BR>
|
|
<P><EM>> gcc -E -D_GNU_SOURCE conftest.c 1>1 2>2

|

</EM><BR>
|
|
<P>Maybe there is a problem with confdefs.h? But this should exist also
|
|
<BR>
|
|
when testing for other headers.
