That will not work.

FPC has a copy of the environment, which it received on startup.
It makes little or no sense to add strings to this, since it is
for internal use only.

If you want to execute another program with a different set of
environment strings, you must use the execve call to specify a
different set of environment variables.

The TProcess component allows you to easily specify the
environment as a TStringList.
