ACK!

In some parts of my app I need to get access to gbak.exe or other tools.
Since there is no environment variable "INTERBASE" set during installation,
I use the registry to locate those binary files:

HKLM\SOFTWARE\Borland\InterBase\CurrentVersion

I've noticed that RC2 still creates this registry entry, as well as a new
entry

HKLM\SOFTWARE\FirebirdSQL\Firebird\CurrentVersion

I think for V1.0 this should be keept to keep existing apps working. Since
Interbase and Firebird could not co-exist on the same machine, it would be
no problem to use the Borland-Registry key.

Just my 0.02 ?
