Option -Zne: Disable JWasm Syntax Extensions

Option -Zne will disable syntax extensions which aren't supported by Masm. Currently these are:

- directive INCBIN

- calling convention FASTCALL

- IDs enclosed in backquotes

- floating-point immediate operands in instructions

- directive OPTION FIELDALIGN

- directive OPTION PROCALIGN

- directive OPTION MZ

- directive OPTION ELF

- directive OPTION WIN64

- directive OPTION FRAME

- directive OPTION RENAMEKEYWORD

- directive OPTION DLLIMPORT

- directive OPTION CODEVIEW

- directive OPTION STACKBASE

- directives PUSHCONTEXT / POPCONTEXT ALIGNMENT

- attribute LABEL for first macro parameter

- member argument for IF[N]DEF and .ERR[N]DEF directives

- integer initializer values for items of type [X]MMWORD

- optional name argument for .DATA, .DATA? and .CONST directives

- forward references in arguments for INVOKEd procedures

- overrides inside square brackets for base/index registers

- Optional Array Size for LABEL Directive

Some directives aren't touched by this option, although Masm won't accept them:

.X64 and .X64p

INVOKE in 64-bit mode

runtime conditional directives .IF, .REPEAT, .WHILE in 64-bit mode

If these directives are to be disabled, it must be done with OPTION NOKEYWORD.
