Subject: [PATCH 1/2] Fix build with gcc -fvisibility=hidden

FGAPI used to be defined to an empty body on non-windows platforms.

Provide a proper definition for gcc to fix build with gcc -fvisibility=hidden.

Add FGAPI attribute to definitions of glutStroke* and glutBitmap* variables,

to make them exported when gcc -fvisibility=hidden is in effect.
