patch for sun workshop compilation bug

[ayan(at)ayan(dot)net]

hello,

i've attached a patch for the following bug
report:

	http://archives.postgresql.org/pgsql-ports/2004-09/msg00008.php

in essence, if configure detects that the
environment is sunos4, s_lock.c should use the
.seg opcode.  otherwise, s_lock.c should use
.section.

i've tested this and i've gotten the latest CVS
source to compile under Solaris 9 using sun's
compiler.
