lib_os

[Nicolas Boulay]

Hello,

I try to clean all the mess in lib_os. My goal is to be as portable as
possible, to use advanced linux stuff for IO, to ease the port of new
architecture  and to remove FS_MIN.

Firstly, i notice sub architecture, that composed our architecture
(Linux, Dos, Windows) :
- c89 basic stuff that is important for small embedded device
- posix stuff for FS_MIN (and other unices) that could be used almost
everywhere (maybe it's not enough under DOS)
- x86 for code use inside the DOS architecture

Linux architecture will derive from posix (2008 version) who derived
it self from c89.

Todays, architecture are set by changing path directory: system.li is
redefine in dos, windows and unix directory.

But if linux derived from posix, i can't defined 2 prototypes with the
same name.

SYSTEM must be SYSTEM_LINUX under linux (SYSTEM_LINUX derive from
SYSTEM_POSIX), but SYSTEM_POSIX must be SYSTEM if the target is posix.
SYSTEM could inherit dynamically to the good prototype, but how to
transmit the information from .lip to the .li code ?

One of the possiblity, will be to set a global variable inside the
compiler to set the target. An other is to defined variable in the
.lip that is "readable" by the .li code this enable the use of a kind
of a generic #define.

Have you a better ideas ? I prefer avoiding to change the compiler code.

Nicolas
