"K&R" C

[msdos6]

I recently got a hold of the sources of Concurrent CP/M-86(circa 1984),
and the system builder, GENCPM is written in a K&R style C. Does GCC
support this syntax? If not, are there any K&R to ANSI converters out
there, or possibly a modern compiler supporting this syntax? Any help
is appreciated.

Thanks,

Have you tried it?

I don't currently have GCC on my computer because I mainly work in
FreeBASIC, and it is pointless for me to have a copy of it at this
period in time. I'll reinstall MinGW and give it a shot.

OK, it will compile K&R style code.

The C90 standard is mostly backward-compatible with K&R (pre-ANSI) C,
so you *probably* won't have any serious problems.

(The bad news: any problems you do have are likely to be subtle ones.)

We must do something. This is something. Therefore, we must do this.

What characteristics of "K&R style C" does it have?

Most of these will be supported in the GNU preprocessor with
"-E -traditional".

With any CP/M-ish software I'd be more concerned about stuff relying on
8- or 16-bit wide values for various things, or architecture-specific
couplings. Last time I touched CP/M I had to deal with Z-80 asm as
well. Hopefully your software is "just plain C".

Is posession of the source code legal?

Better check and make sure. Just becasue its old does not make it legal
unless its owner at one time or another released it to the public
domain.

All the assembly is in the BDOS, XIOS, and other main parts of CP/M.
The CP/M generation tool is made out of 100% C code, so it shouldn't
really matter.

It is legal. Caldera released the source code quite a while ago. My
only real restriction with the code is that I cannot use it for
proprietary purposes.

Thank you everyone, for your help.

Does GCC support this syntax? If not, are there any K&R to ANSI
converters out there, or possibly a modern compiler supporting
this syntax? Any help is appreciated.

Where is this source?
