SVR2 compilers on the 3B2 have had #ident since (at least) pcc2.

It's the ".comment" section (as opposed to .text, .data, or .bss).

< That way, SCCS IDs are in the object file (and in the source file, by virtue

The command that diddles with this is  `mcs' (manipulate comment section).

< Some systems implement it but don't pass it through to the compiler;

This is mighty nice of them -- I like #ident.
