Subject: [ng] check: support conditional $(TEST_EXTENSIONS)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=508270d52ac913fe2260d0821d69c249f65450f6;p=thirdparty%2Fautomake.git

[ng] check: support conditional $(TEST_EXTENSIONS)

That is pretty easy to do with the current code base; just ...

* automake.in (handle_tests): ... stop erroring on conditional contents
of TEST_EXTENSIONS, and move the definitions of a default TEST_EXTENSIONS
variable ...
* lib/am/parallel-tests.am: ... in here.
* t/test-extensions-cond.sh: Rewritten to adapt to the new semantic.
