I suspect you'll fix the problem with UINT if you just have a file named 'typemap'(located in the same directory as the xs file) that contains simply: 
UINT T_UV

That should tell perl to treat "UINT" as a "T_UV" (unsigned int) .... and perl knows all about the "T_UV" type and how to deal with it, courtesy of perl/lib/ExtUtils/typemap.

(Btw, you don't need to include windows.h - it has already been pulled in by perl.h.)

Here's a little Inline::C demo that works only if said typemap is present: 
# try.pl
use warnings;
use strict;

use Inline C => Config =>
    BUILD_NOISY => 1;

use Inline C =><<'EOC';

UINT hello() {
  UINT x = 17;
  return x;
}


EOC

$x = hello();
print $x; 

# On Windows:
# Outputs 17 if typemap is present,
# Otherwise outputs "Undefined subroutine &main::hello called at try.p
+l line 16."
