/*
|
|
* 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.
