Bug report for Octave 2.1.64 configured for i686-pc-linux-gnu

Description:
-----------

   * If the configuration process does not define HAVE_USLEEP nor 
HAVE_SELECT,
   the compilation stops with the following error:
   octave_usleep()
   cutils.c: In function `octave_usleep':
   cutils.c:108: error: `fd' undeclared (first use in this function)
   cutils.c:108: error: (Each undeclared identifier is reported only once
   cutils.c:108: error: for each function it appears in.)
   cutils.c:104: warning: unused variable `pfd'

Repeat-By:
---------

   * I had to manually change config.h to uncomment HAVE_SELECT and
HAVE_USLEEP to trigger this bug.


Fix:
---

   The following patch fixes the problem: it just renames fd to pfd:
