Comment 2 for bug 945368

Yep, the errors from my previous comment are why this isn't building.

vnc4 has an old copy of the Xserver included in it. The file unix/xc/programs/Xserver/hw/xfree86/common/compiler.h includes definitions for inw(), inb() which conflict with ones provided in sys/io.h on arm.

Current Xserver's compiler includes preprocessor conditions to hide the declarations. It also includes this comment to explain what it's doing:

#elif defined(__arm__) && defined(__linux__)
/* for Linux on ARM, we use the LIBC inx/outx routines */
/* note that the appropriate setup via "ioperm" needs to be done */
/* *before* any inx/outx is done. */
#include <sys/io.h>
...

So, it looks to me like this code needs to be ported over to vnc4's compiler.h.

Theoretically should be straightforward work, but I've got some higher priority items I need to tend to first so if anyone else wants to take a stab at it, go for it.
