Objects and GPC_(re)

Hi everybody, hi African Chief!

It seems that I am no more the only one who uses Objects.  :-)

According to The African Chief:

That's strange because when I put TObject below in a separate Unit
everything compiles fine.  However the resulting code is buggy.  :-(
I will investigate this.

Did you recompile the Unit?  The GPI file format changes with every
new alpha GPC.

I see.  You have detected a bug ... even two bugs.
Thanks for reporting them!

The `--borland-pascal' switch has no effect on this. 
You do not need to enable Objects, but vice versa, if you specify one of
`--standard-pascal·level-0', `--standard-pascal', `--extended-pascal', or
`--ucsd-pascal', you *disable* OOP.
