Determine conclusively whether BCMath is a requirement

[sneurlax]

I strongly suspected that PHP's inconsistent handling of 64 bit integers was to blame for failing tests recently, but now that I've resolved the errors I was facing, BCMath functions should be stripped and tests run again on both 32-bit and 64-bit systems in order to conclusively determine whether BCMath functions are requirement, after all.

• Test 32-bit Linux

• Test 64-bit Linux

• Test 32-bit Windows

• Test 64-bit Windows
