Ultrix 4.0.1, vaxstation 2000:
In /usr/include/math.h I found this line:
#if defined(GFLOAT) || CC$gfloat
^^^^^^^^^
And this is not the only one. Why can't Digital leave $ in VMS
where it belongs?
Gcc complains. And if I look in the C book it says that an identifier
can only be [a-zA-Z_][a-zA-Z_0-9].
Is there a fix for gcc, or is there another way to fix this?

The header file is not designed for gcc. A vendor is allowed to organize its standard headers in any manner for use with its compier, as long as it compiles conforming programs correctly -- the headers don't even have to exist as files. Furthermore, a compiler that does not claim ANSI conformance does not have to do anything at all, though it does more than it has to. (This is not the company's opinion.) >Is there a fix for gcc, or is there another way to fix this? gcc has a "fixincludes" script, but if you intend to continue using the supplied cc as well, then you don't want to change the headers in /usr/include. (This is not the company's opinion.) My suggestion: You might create another directory, /usr/gcc_include or something, and always instruct gcc to search the other directory first. (I once did this at another employer. It was not that company's opinion either.) -- Norman Diamond diamond@tkov50.enet.dec.com If this were the company's opinion, I wouldn't be allowed to post it.

While we are on the subject, check out sys/file.h: #ifdef KERNEL && !defined(_POSIX_SOURCE) According to me and to gcc this is garbage. >Is there a fix for gcc, or is there another way to fix this? Remove "|| CC$gfloat" from the include files. Alternatively, copy the files to /usr/local/lib/gcc-include (or whatever) and fix it there. -- Sjaak Schilperoort JW_Schilperoort@pttrnl.nl PTT Research Neher Laboratorium ...!hp4nl!dnlunx!sjaak Leidschendam, Netherlands schilperoort@hlsdnl5.bitnet

I'd say they intend to merge VMS and Ultrix... Is this :-) or :-( ?avolio@decuac.dec.com (Frederick M. Avolio) (01/25/91)
Oh, gee.... The blooming $ junk is in ther I imagine because some sloppy programmer left it there. Much s/w in Digital is developed on RISC platforms (UNIX) and then moved to VMS. Normally one sees conditional compiles, etc. that contain VMSisms, but sometimes they slip through otherwise. It is much easier to bend UNIX to accomodate VMS than the other way around :-) Fred

The idea behind the '$' in VMS tokens/filenames etc. Was that the '$' was
"reserved" to DEC, and therefor wouldn't ever clash with a user or
thrid-paty specified token/filename etc.
Unfortunately, until recently the DEC universe has been revolving around
VMS (now it's a binary star system), so extracting all the VMS'isms from
stuff moved to Ultrix is a lot of work.

Quoting from the GCC manual:
`DOLLARS_IN_IDENTIFIERS'
Define this to be nonzero if the character `$' should be allowed

Shouldn't that be `DOLLARS$IN$IDENTIFIERS'?frank@croton.enet.dec.com (Frank Wortner) (01/30/91)
