No description
The sequence EXTERN, GLOBAL, definition would fail, because the EXTERN would create a pseudo-segment and consider it a definition, whereas GLOBAL would set change it to a global definition, but leaving the definition existing, which is not the normal case for a GLOBAL symbol (define_label would not be called.) Therefore, explicitly "undefine" the symbol by setting defn.defined to 0, as it would be after a GLOBAL statement, as as it is when an EXTERN statement is followed by a definition (causing it to be implicitly promoted to GLOBAL.)

NASM, the Netwide Assembler
Many many developers all over the net respect NASM for what it is: a widespread (thus netwide), portable (thus netwide!), very flexible and mature assembler tool with support for many output formats (thus netwide!!).
Now we have good news for you: NASM is licensed under the "simplified" (2-clause) BSD license. This means its development is open to even wider society of programmers wishing to improve their lovely assembler.
Visit our nasm.us website for more details.
With best regards, the NASM crew.
