dnl If the test passes, will execute ACTION-IF-FOUND. Otherwise, ACTION-IF-NOT-FOUND.
dnl Note : This file will be likely to induce the compiler to create a module file
dnl (for a module called conftest).
dnl Depending on the compiler flags, this could cause a conftest.mod file to appear
dnl in the present directory, or in another, or with another name. So be warned!
