In fact, what cases is this supposed to be matching? All the documented --thingydir options are handled explicitly earlier in the case statement. Paolo, you added this case in commit 6bde81cb0, but the commit message doesn't give any rationale; what's it for? -- PMM

There were some --*dir that are supported by Autoconf and not by QEMU configure. The aim was to let QEMU packagers use the rpm (or similar) macro that overrides directories for their distribution.

Can we list them explicitly with a comment about why we accept but ignore them, please? -- PMM

I guess the list is the following: --mandir=PATH install man pages in PATH --datadir=PATH install firmware in PATH --docdir=PATH install documentation in PATH --bindir=PATH install binaries in PATH --sysconfdir=PATH install config in PATH/qemu http://www.gnu.org/prep/standards/html_node/Configuration.html says that it should also handle the following list: --bindir --sbindir --libexecdir --sysconfdir --sharedstatedir --localstatedir --libdir --includedir --oldincludedir --datarootdir --datadir --infodir --localedir --mandir --docdir --htmldir --dvidir --pdfdir --psdir Do we need anything of these?
