 According to my experience and both,
AC_RUN_IFELSE() as well as AC_TRY_RUN() it replaces fail only if
action-if-cross-compiling is not specified. If it is specified, it is used but
usually this action is just a fallback and the test is still not ran.

 I don't think we're speaking about the same thing as it seems extremely
unlikely that you're running your test suite from configure. So, to clarify: I
am speaking about tests done in configure, not about any other tests built
during the program build process.

 They're not failing, they simply are not ran by configure.
