Hi Vladimir,

thans for the swift response.

We use a mix of MSVC, gcc and the occasional vendor compiler.  Target
systems are smart phones in a number of varieties, usually something
based on ARM and WinCE.

A good interface for cross compilation would probably distiguish between
the host system and the target system, and know about architecture and
platform respectively.  For instance, one could have attributes
"host-architecture", "host-platform", "target-architecture",
"target-platform".  I'm tempted to even suggest a "target-model"
attribute, some things in the build process depend on the specific model
of the phone, for instance because they depend on the screen size, or
buttons present.

Both architectures and platforms would ideally form some kind of
hierarchy each, e.g. "arm926" is a "arm9" is a "arm" architecture; or
"WinCE50" is a "WinCE" is a "Win32" platform.  I'd like to say somewhere
"I'm now compiling for this arm926 on WinCE50", and then in some library
say "use this file on PowerPC, and that file on ARM".

Andreas
