<sys/select.h> on OSF/1

[Bruno Haible]

On OSF/1 4.0, <sys/select.h> exists but provides only a forward declaration
of 'struct timeval', no definition of this type. This leads to this error:


cc -nodtk -O -std -std -DHAVE_CONFIG_H -I. -I..  -I. -I.  -I.. -I./..  
-I../gnulib-lib -I./../gnulib-lib  
-I/nfs/visu/telecom/users/haible/gnu/arch/alpha4/include   -c test-sys_select.c
cc: Error: test-sys_select.c, line 193: In this declaration, "tv0" has no 
linkage and is of an incomplete type.
  static struct timeval tv0;
------------------------^


I'm applying this stopgap measure. Of course it would be better to work
around this problem in the sys_select module, rather than in the test. Feel
free to do so if you have time for it.

        * doc/posix-headers/sys_select.texi: Mention 'struct timeval' problem.
        * tests/test-sys_select.c: Include <sys/time.h>, for struct timeval.
        Needed on OSF/1 4.0.
