280	include os2safe.h by default	KO Myung-Hun	Silvan Scherrer	"Hi/2.

Currently, os2safe.h should be included manually. This is meaningful if a program intend to use a high memory. But some libraries does not consider a high memory at first. 

So when enabled -Zhigh-memory in one program, it causes many problem when linking against non-high-memory-enabled libraries, especially without including os2safe.h.

However, if os2safe.h is included by default, it is possible to avoid this problem. The libraries without considering a high-memory, can be linked with a high memory enabled programs or libraries.

In addition, even tough os2safe.h is included without -Zhigh-mem, it has no side effects at all, but a little overhead to copy between the source and the buffer."	defect	closed	highest	libc-0.6.6	libc	0.6.5	blocker	fixed
