#1107: Compiling with OpenBSD's gcc-4.2.1 produces 2 warnings when compiling
posixunix.c

 Reporter:  ckeen           |       Owner:       
     Type:  defect          |      Status:  new  
 Priority:  critical        |   Milestone:  4.9.0
Component:  core libraries  |     Version:  4.8.x
 Keywords:                  |  
----------------------------+-----------------------------------------------
 The line numers differ from building the latest dev snapshot and master
 but the source code line is the same:

 {{{
 posixunix.c:9214: warning: array size (4) smaller than bound length (1024)
 }}}

 The line in question contains:

 {{{
 t3=C_curdir(t2);
 }}}

 The second warning is generated for the line:

 {{{
  t2= C_do_readlink(t1,((C_word*)t0)[2]);
 }}}

 Compiling with a newer gcc (4.8.2) from ports does not show these, so this
 might be a compiler optimisation bug in gcc or a bogus warning.

 Compiling with -O0 still produced the warnings.

 This has been observed on a 32-bit i386 Openbsd 5.5-current machine.
