Xsun fails compile on SunOS4.1.1

No, with the new SunOS 4.1[.x] *operating system*, Sun has changed the
value of the constant.  (Yes, I know this for a fact - I'm the guy who
changed the value....)

Yup.

The good news is that the whole reason that grot is being done is that the
pre-4.1 driver lied, and claimed that a Type 4 keyboard was actually a
Type 3 keyboard.  The new driver doesn't do so, so the fix should simply
be to ensure that TYPE4KEYBOARDOVERRIDE isn't defined when compiling with
the new 4.1[.x] driver, thus removing that code entirely.

You can try something such as replacing the code that defines
TYPE4KEYBOARDOVERRIDE with

/*
 * The Sun 386i has system include files that preclude this pre SunOS 4.1
 * test for the presence of a type 4 keyboard however it really doesn't
 * matter since no 386i has ever been shipped with a type 3 keyboard.
 * In addition, the same is true of the 4.1 driver, but it really
 * doesn't matter there, either, because the 4.1 driver tells you whether
 * you have a Type 3 or a Type 4.

#if !defined(i386) && HOLE != 0x302
