	This sounds suspiciously like a phone call I got this afternoon. :-)

	Inside Mac V is wrong. The interface to SysEnvirons is

	FUNCTION SysEnvirons (version : Integer; VAR env : SysEnvRec) : OSErr;

There is no such type as "SysEnvRecPtr", unless you define it yourself,
and attempting to pass one as a VAR argument to SysEnvirons will result
in havoc.

This necessary function interface and data types are built into THINK Pascal.
