is run-time path translation standard

[Roumen Petrov]

Dear Wine developers,

Starting from version 2.x the libtool would like the create an
environment where user to be able to run win32 programs.
The former version 1.5x has this capability, but with some limitation in
case of cross-compilation environment.
The current libtool HEAD revision contain code that create binary
executable (C-wrapper). This wrapper executable setup environment and
run the real executable. The development in case of cygwin/msys native
environment is finished and now on the road is cross-compilation.
Lest see recent libtool 2x discussion started here:
http://lists.gnu.org/archive/html/libtool-patches/2008-05/msg00044.html


The question if about translation at run time of items in PATH 
environment variable. My test show that we can add absolute paths from 
build system to the PATH and at run time those paths are translated to 
the paths in emulated environment. Is this translation documented, i.e. 
standard or it is just a "side-effect"?
If translation is non-standard, could Wine team confirm that will keep it ?
