[Bug classpath/35536] New: ioctl and FIONREAD on Cygwin

[mario dot latronico at gmail dot com]

On Cygwin (on X86) ioctl on FIONREAD returns EINVAL on the errno variable
instead of ENOTTY. So on the file native/jni/java-nio/gnu_java_nio_VMChannel.c
the function Java_gnu_java_nio_VMChannel_available (JNIEnv *env,               
                       jclass c __attribute__((unused)), jint fd) should
control also for EINVAL on errno variable. For example, starting from line 1601
(from today cvs):

if (ioctl (fd, FIONREAD, &avail) == -1)
{
#if defined(ENOTTY) && defined(HAVE_FSTAT)
  if (errno == ENOTTY)


the last line on cygwin should be 

if (errno == ENOTTY || errno = EINVAL)


The configure string is :
./configure --without-x --disable-gtk-peer --disable-gconf-peer
--disable-plugin
