[fpc-devel] Error seeking resources when compiling with {$R *.res}

[NetSpirit]

I am supply {$R *.res} only as generic example. With an {$R filename.res}
the same problem.

I know this cases when compiling project:
1) Units available only in *.ppu/*.o (etc., compiled units).
   == Resource, linked by {$R} in these units must be searched relative to
these compiled units.
2) Available both - source *.pp and compiled *.ppu, but *.pp unmodified,
so used *.ppu for linking.
   == a) Resource, linked by {$R} in these units must be searched relative
to these compiled units.
   == b) If not found - read source *.pp and search resource relative to
this *.pp.
3) Available both - source *.pp and compiled *.ppu, but *.pp modified OR
available only source *.pp and it recompiled.
  == Resource, linked by {$R} in these units must be searched relative to
*.pp.

In FPC 3.0.0 approach (1) and (2a) don't work, (2a) and (3) works
partially - only the first compilation succeeded, when path's to *.res
resolved by reading source *.pp files. The next compilations fails becouse
*.res searched relative to *.ppu files, but we need put this *.res here
manually. In previous versions there is no such behavior.

> {$R *.res} in ONLY allowed for the project file.
> You should never try to link in a * resource in a unit, because the *
resolves to the main project name.
> Same as in Delphi.
> If you need a resource in a unit, resolve the full name, like {$R
myunit1.res}
> The main *.res is available over all units in a project.

>> CONDITIONS
>> Unit file contains {$R *.res} directive. File *.res exists in the same
directory where *.pp file for unit exists.
>> Compiled units resides in subdirectory, for example called
>> 'units' (-FU command line switch).
>> DESCRIPTION
>> When project with such unit compiled first time - all work as
>> expected. Compiled *.ppu files goes to 'units', resulting binary created.
>> On the second and next compilations we encounter en error:
>> "Error: Can't open file 'D:\projectpath\units\Unit1.res'".
>> This error is a result of searching *.res in a directory where
>> compiled units exists, but not in a directory where unit source file
resided.
