This all looks good, and your output from running the "configure"
script matches what we get on our Linux system.

On our Linux platform, we see no such error using the same compiler
and compile flags.  From a previous support reply to this question:

  The above indicates that the C compiler couldn't find the header-file
  "linux/errno.h" that its own header-file "/usr/include/errno.h"
  references.  This indicates a problem with the C installation (a C
  implementation must be able to find all the header files that it
  references).  I would show this problem to your system administrator,
  complain to the vendor (RedHat), and/or reinstall the C implementation.

Looking at /usr/include/errno.h on our Linux system, it #includes
<bits/errno.h>, which in turn #includes <linux/errno.h>, and we have
the file "/usr/include/linux/errno.h":

  -rw-r--r--    1 root     root          908 Apr  8  2001 
/usr/include/linux/errno.h

It appears that this file is missing from your installation, so any C
program that tries to #include <errno.h> will get this error.  If you
find this file has been installed in some other nonstandard place, you
might be able to get things to compile by defining
CPPFLAGS='-I/some/wierd/include/place' before rerunning the configure
script, but I think it would be better to fix the installation of the
include files ...
