* PKGBUILD:
- add (make)dependency to libiconv (apparently new with m4 1.4.19)
- remove INSTALL directive, since routines in m4.install are
automatically covered by makepkg
** prepare:
- remove any M4 macro patches to make running 'autoreconf' obsolete
- add patches for test suite
** build:
- apply VPATH build
- fool configure that gcc is CYGWIN to be able to use CONFIGURE straight
out of the box (without patching code bits missing MSYS as system).
For GNULIB this is a nightmare.
- enable multi-threading
**check:
- pass list of tests still failing after applying patch skipping tests
due to permission access issues
(see 0003-m4-1.1.19-skip-tests-when-temp-directories-cannot-be-generated.patch)
on to 'make check' via variable XFAIL_TESTS. This applies to GNULIB
tests checking the environment only, but not M4 features, though.
- NB: All tests except those in variable XFAIL_TESTS succeed.
* 0001-m4-1.4.19-tests-refine-error-messages.patch:
- added, no functional change
* 0002-m4-1.1.19-skip-tests-when-temp-directories-cannot-be-generated.patch:
- added, skip test failing in the prep phase when generating directories
with particular access rights
* m4.install:
- removed (since obsolete as functionality covered by pacman/makepkg)
* m4-1.4.18-msys2.patch:
- removed, since configure is used straight out of the box being fooled
that a CYGWIN compiler is used
