[PD] How to deal with externals for both 64 and 32-bit Pd

[Pierre Alexandre Tremblay]

What worries me most, with FluCoMa in head, is what is the horizon to support this - in other words, when is 32 and 64 will be shipped as equal.

There is no more dev resources apart from some free time by yours truly for all the stuff so I need to plan carefully… in years! So if anyone on the dev team knows the horizon what would be appreciated
