Subject: The MSVC x86_64 compiler defines long as 32-bits.
X-Git-Url: http://git.subgeniuskitty.com/pforth/.git/commitdiff_plain/58a4c23bbd72fd0fde36266e8c9faa4e199d1232?hp=529bb4e23b94186596ca0e3f5d295b0be95d4fad

The MSVC x86_64 compiler defines long as 32-bits.
This means '1L' is 32-bits and a 62 bit shift on a 32-bit
value is UB which resulted in a 0 for the FP_DHI1 value.
