Firebird Embedded on MacOSX

Based on a document written by Fulvio, a while ago, I finally spent time writing a make file that will automatically create an embedded version of Firebird that will run on MacOSX as a bundle. All you do is make a normal build of Firebird Classic and then use this make file to create the Firebird.app folder which is set up in a way that allows you to access a database via isql for example without the need for a full framework. The make file detailed below was written for Firebird 2.5.x
