No it does not.

Fatal: Compilation aborted
Error: C:\devel\fpc\3.2.0\bin\i386-Win32\ppc386.exe returned an error exitcode

The compiler (3.2.0RC1) first tries the specified path in -Fu:
(SYSTEM)   Loading unit SYSTEM
(SYSTEM)   PPU Name: C:\pp\units\i386-win32\rtl\system.ppu

It then immediately aborts.
It never looks for system.ppu in the folder specified in the fpc.cfg
of this compiler.

Please look at the context.
This is the trunk compiler.
I point it (erroneously) tot the system.ppu of fpc3.2.0RC1
It finds it, determines it's invalid, and then proceeds to find the
correct one (specified in fpc.cfg of the trunk compiler) and
succesfully builds the test program.
(I did not iclude the snippet where it finds the correct one, since I
thought this would be obvious, as it succeeds in compiling)


Michale then replied:

To which I later replied:

The question remains: why a fatal error if fpc 3.2.0 encounters the
system.ppu of fpc trunk, where fpc 3.0.4 does not.
Is that a bug in fpc 3.2.0RC1?

(So, we're all up to speed now)
