BGLC
From FSDeveloper Wiki
BGLC stands for BGL Compiler and is the official compiler that Microsoft provided with their SDK to generate BGL files. The last official version was provided with the FS2002 SDK. For FS2004 Microsoft did not release a new version, but the community provided an updated version that allows compilation of objects according to the FS2004 SDK.
