This doesn't help me install Tk under Strawberry Perl 5.38.2. Issuing the command
cpan Tk
or any other variation thereof, cranks through the usual thousands of lines of incomprehensibility, including some red errors early on, maybe on something named "pmop" or something like that... But the real point of failure is this incomprehensible C compilation error:

This is very strange as this is the third successive line of pretty much the same format: "#define _____ (1<<_)" , but the first two lines are apparently acceptable as they stand. The only outstanding difference in this line is that "ControlMask" as a string is long enough that it moves the definition "(1<<2)" to the next tab stop, as compared to the two preceding lines.
I also can't reproduce the error in a simple test program that simply does a "#include tk.h".
