x64 dll hijacker made using this might cause errors on some Windows flavours & build configs due to wrong stack alignment in the "PRX_EXPORT64 macro procname:req, ordinal:req" defined in each asm file, causing a #GP fault on instructions needing 16 byte boundary (movaps), it happened some dozen chained calls from the unaligned stack place, in system area.

Fix:
alloc_stack 20h to alloc_stack 28h
....
add rsp, 20h to add rsp, 28h
in the macro function definition of the asm file
