Comment (by fbissey):

 Cannot say I like the macro in style or substance. But looking at your
 configure.ac I can see why you have the current behavior. I think it is
 wrong and I think using AC_CHECK_LIB is good. Now I see where the mangling
 issue comes from. It is exactly the opposite of what I say don't work for
 sure, your test is compiled with a C compiler which doesn't understand
 that the symbols are mangled. Somehow the symbol that you were testing
 previously must have been from a part of the library in C.

 We can solve that problem by switching to the c++ for the test
 [https://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node
 /Language-Choice.html] and then reverting back for the rest. I may have
 closer look tomorrow and post a pull request on github.
