Also notice that the recent changes have fixed the long-standing (almost two years old!) automake bug#7441.

This has simplified the compilation process, and + more importantly made it less brittle. The downside is that emacs is + now invoked once for each '.el' files, which cause some noticeable + slowdowns. These should however be mitigated on multicore machines + (which are becoming the norm today) if concurrent make ("make -j") + is used. + + - Elisp files placed in a subdirectory are now byte-compiled to '.elc' + files in the same subdirectory; for example, byte-compiling of file + 'sub/foo.el' file will result in 'sub/foo.elc' rather than in + 'foo.elc'. This behaviour is backward-incompatible with older + Automake versions, but it is more natural and more sane. See also + automake bug#7441. + + - The Emacs invocation performing byte-compilation of '.el' files honors + the $(AM_ELCFLAGS) and $(ELCFLAGS) variables; as typical, the former + one is developer-reserved and the latter one user-reserved. + + - The 'elisp-comp' script, once provided by Automake, has been rendered + obsoleted by the just-described changes, and thus removed. + * Changes to Automake-generated testsuite harnesses: - The parallel testsuite harness (previously only enabled by the
