So my conundrum is this: in automake-1.13, the default switched from serial testing to parallel testing. The only way I can see to disable this is to add "serial-tests" to my AM_INIT_AUTOMAKE. However, my AM_INIT_AUTOMAKE also only requires version 1.11.6, which I'd like to continue supporting, and these older versions of automake will barf on the invalid option "serial-tests" (I also tried "no-parallel-tests", but that's also invalid).
There doesn't seem to be a way to set up my configure.ac such that my tests will run in serial mode on both older and newer versions of automake (1.11.6 -> 1.13) without causing an automake error (invalid option) in 1.11.6. Am I missing some tricky method of working around this, or is it just not possible?
