The failing test is the tooLong test which checks that assign on 64 bit types
gets rejected. The compiler output is:

../tooLong.st:15:2: error: #error variable 'long l' cannot be assigned to a PV
(on the chosen target system) because Channel Access does not support integral
types longer than 4 bytes. You can use 'int' instead, or the fixed size type
'int32_t'.
# ../tooLong.st:18:2: error: #error variable 'unsigned long ul' cannot be
assigned to a PV (on the chosen target system) because Channel Access does not
support integral types longer than 4 bytes. You can use 'unsigned int'
instead, or the fixed size type 'uint32_t'.

This is correct; the problem is that the perl script thinks the test should
succeed, not fail, since the EPICS_HOST_ARCH does not match against the string
'64'. So, I rather have to adapt the expectation and refine the heuristic that
tries to determine 64-bit-ness of the host arch. What is the value of
EPICS_HOST_ARCH for your system?

Cheers
Ben
