Certainly not. Modula-2 was/is not depending on any CPU specifics, 
certainly not on anything x86, considering that the first computers 
Modula-2 ran on were the Xerox Alto and the Lilith, using M-Code, and 
both not even a remote connection to anything x86. And a lot of 
non-Wirth Modula-2 implementation ran on Motorola 68k before I can 
remember to have seen the first x86 implementation (not sure if it 
was FST or XDS)...
