macro doesn't align unicode strings declared in

Code:

invoke   somefunc, "somestring"

on 2 byte natural alignment as it required by some APIs. RCE showed STATUS_DATATYPE_MISALIGNMENT on such 1-byte aligned strings.

WIN32W[X[P]].INC
Should be changed to

Code:

ALIGN 2
nop
    call ..continue
    du value,0
    ..continue:

I think this is a good suggestion.

However this may be missed by Tomasz in this thread. Perhaps a mod can move and sticky it into Compiler Internals?
