OpenBSD display various warnings about the use of an undefined __HAIKU__:
CC ui/egl-context.o
In file included from /usr/X11R6/include/epoxy/egl_generated.h:10:0,
from /usr/X11R6/include/epoxy/egl.h:46,
from include/ui/egl-helpers.h:5,
from include/ui/egl-context.h:5,
from ui/egl-context.c:3:
/usr/X11R6/include/EGL/eglplatform.h:128:7: warning: "__HAIKU__" is not
defined [-Wundef]
#elif __HAIKU__
^
CC ui/egl-helpers.o
/usr/X11R6/include/EGL/eglplatform.h:128:7: warning: "__HAIKU__" is not defined
[-Wundef]
CC ui/egl-headless.o
/usr/X11R6/include/EGL/eglplatform.h:128:7: warning: "__HAIKU__" is not defined
[-Wundef]
This is due to a old <epoxy/egl_generated.h>:
70 #if defined(_WIN32) || defined(__VC32__) && !defined(__CYGWIN__) &&
!defined(__SCITECH_SNAP__) /* Win32 and WinCE */
...
108 #elif defined(__unix__) || defined(__APPLE__)
128 #elif __HAIKU__
134 #else
135 #error "Platform not recognized"
136 #endif
Kludge this by adding a check to ./configure: if this warning occurs,
define __HAIKU__ from the CFLAGS.

This is ugly, hopefully someone can come with a clever idea :)
