From 0df037543f28ce0af60b427bba126c773eb76426 Mon Sep 17 00:00:00 2001 From: tma Date: Wed, 12 Sep 2007 18:02:38 +0000 Subject: * Revert 1176 -- MinGW's headers are too old *sigh* * Revert to using literal function pointers for GL extensions rather than PFN* typedefs as some platforms' headers are broken enough that they prevent SDL_opengl.h from fixing things up if the PFN* typedefs are missing git-svn-id: svn://svn.icculus.org/quake3/trunk@1177 edf5b092-35ff-0310-97b2-ce42778d08ea --- code/renderer/qgl.h | 27 +++++++-------------------- code/renderer/tr_backend.c | 16 ++++++++-------- code/renderer/tr_image.c | 6 +++--- code/renderer/tr_init.c | 8 +++++--- code/renderer/tr_local.h | 1 + code/renderer/tr_shade.c | 4 ++-- code/renderer/tr_shader.c | 2 +- 7 files changed, 27 insertions(+), 37 deletions(-) (limited to 'code/renderer') diff --git a/code/renderer/qgl.h b/code/renderer/qgl.h index 7ba2658..dcbc04d 100644 --- a/code/renderer/qgl.h +++ b/code/renderer/qgl.h @@ -28,8 +28,13 @@ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA #include "SDL_opengl.h" -extern PFNGLLOCKARRAYSEXTPROC qglLockArraysEXT;
