[DTrace-devel] [PATCH v2] configure: accept standard installation directory options

[Nick Alcock]

On 5 Mar 2026, Kris Van Hees spake thusly:

> Even though we do not use them, the GNU Coding Standards expect configure
> to accept the following installation directory options as well:
>
> 	--libexecdir=PREFIX/libexec	Program executables directory
> 	--sysconfdir=PREFIX/etc		System configuration directory
> 	--sharedstatedir=PREFIX/com	Arch-independent data directory
> 	--localstatedir=PREFIX/var	Runtime system data directory
> 	--runstatedir=PREFIX/var/run	Per-process data directory
> 	--oldincludedir=PREFIX/include	#include directory (non-gcc)
> 	--infodir=DATADIR/info		Info documentation directory
> 	--localedir=DATADIR/locale	locale specific data directory
> 	--htmldir=DOCDIR		Html documentation directory
> 	--pdfdir=DOCDIR			PDF documentation directory
> 	--psdir=DOCDIR			PS documentation directory
>
> This patch also redefines some of the make variables in terms of one
> another now that a larger set is supported.

Nice!!! (I presume the tabs are actually aligned, but thrown off by
diff and quoting prefixes.)
