["OBATA Akio" <obache%netbsd.org@localhost>]

Hi,

Attached patches are acceptable for devel/bmake?

patch-1:
Interix is known as that it sometimes fail to fork(2) with EAGAIN even no heavy 
situation.
This patch let to retry vfolk(2) when EAGAIN is occurred, same manner as pdksh 
doing.

patch-2:
On Haiku, failed to unit-test.
Set MACHINE_ARCH for i386.

For Haiku, remain one problem, lack of ar.h,
no ARMAG, SARMAG and struct ar_hdr definitions, then failed to compile arch.c.
What is the right way to resolve this issue?
