[PD] [PD-announce] pd 0.50-0 test1 released

[Christof Ressi]

Good idea! I think it's mostly a Windows issue since macOS and Linux have been 64-bit for ages. On Windows this is how you can get the architecture:

1) open the file in binary mode
2) read the BYTE at location 0x3C to get the COFF header offset
3) seek to the COFF header offset
4) check that the first 4 bytes match the character sequence "PE\0\0" -> Windows binary
5) the next WORD is the machine type
6) 0x8664 -> x64, otherwise 32bit

We would only need to do this check if LoadLibrary fails.
