- * This file is necessary for the *nix version of "freeglut" because the
- * original GLUT defined its font variables in rather an unusual way.
- * Publicly, in "glut.h", they were defined as "void *". Privately,
- * in one of the source code files, they were defined as pointers to a
- * structure. Most compilers and linkers are satisfied with the "void *"
- * and don't go any farther, but some of them balked. In particular,
- * when compiling with "freeglut" and then trying to run using the GLUT
- * ".so" library, some of them would give an error. So we are having to
- * create this file to define the variables as pointers to an unusual
- * structure to match GLUT.

- /*
- * freeglut_internal.h uses some GL types, but including the GL header portably
- * is a bit tricky, so we include freeglut_std.h here, which contains the
- * necessary machinery. But this poses another problem, caused by the ugly
- * original defintion of the font constants in "classic" GLUT: They are defined
- * as void* externally, so we move them temporarily out of the way by AN EXTREME
- * CPP HACK.
