RE: gnubol: How do we parse this language, anyway?
OK, now I am totally confused. One of the notes on this topic said,
"Three compilers, Micro Focus on alpha/tru64, Fujitsu on MS Windows and
Wang ReSource either on HP/UX or AIX accepted such programs without
warnings."
I just tried it (the attached program) with Fujitsu and it gets just as
severe a message as I would expect. Now, I know that Micro Focus *will*
accept this - and issue a FLAGSTD (FIPS) message indicating that it is an
extension.
If you want to add it as an extension (which I still don't understand WHY) at
least try and figure out how many other compilers really DO support it (and
as I expected, don't count Fujitsu in that list - nor IBM I am positive - but
will wait to hear the "official" version on).
NOTE: There really are "useful" extensions that I would fully support -
don't think that I am "anti-any extension" - but this is just one that I
don't see the need for, nor the advantage of having.
P.S. For example, I will certainly support the following fairly common
extensions:
GoBack
Comp-3 (as Packed-Decimal)
Comp-1 and Comp-2 (as floating point)
Comp-5 (as defined in X/Open CAE)
Trunc/Notrunc compiler option
Use of apostrophe (single quote) in addition to quotation mark
inline comments
z-literals (null-terminated strings - can also be done with Concatenation
expressions)
and MANY others (from IBM, from Micro Focus, from X/Open, from draft of
next Standard, etc)
