Subject: Makefile.am, configure.ac, ident.c -> linux.c: System specifics.
X-Git-Tag: 1.0.0~21
X-Git-Url: https://git.distorted.org.uk/~mdw/yaid/commitdiff_plain/38b211f2a0e292153413e6edb543308f1443d0de

Makefile.am, configure.ac, ident.c -> linux.c: System specifics.

Rename `ident.c' to indicate that this is where the system-specific
machinery lives, and provide build system support for other platforms
should they be contributed.
