[Libsysio-commit] HEAD: libsysio Rules.make configure.in

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv8149

Modified Files:
	Rules.make configure.in 
Log Message:


Merging in the defer-cwd branch. These changes include:

+ Carry full stat info in the inode now
+ Use that stat info (careful with intents!) instead of calling getattr
+ Cached attributes for the native driver
+ Abstracted and localized system call defs (see .../include/native.h)
+ The ability to defer path traversal to the "current working directory" unless
	and until a relative pathname is specified. This alters _sysio_boot
	to take an extra parameter (the init cwd) and must be configured
	with "--with-defer-init-cwd".
