Detecting object file format |

Dear all,
Sorry if the question is trivial. I am wondering how one should proceed
to determine the object file format used on a target system in a
configure.ac script?
To be more precise: I am working on a project which tests this by trying
to compile a C program that has a different behaviour according to
whether __ELF__ is defined or not. I am supposed to replace a hand-written
configure script that uses this program by an autoconf-generated one
for this project and I wonder how I should deal with this test.
I notice that config.guess does probe for __ELF__ but I don't know
whether there is a way to access this information from within the
configure.ac script, or whether I will perhaps need to write a
dedicated test that compiles the program as in the original project?
Many thanks in advance for any hint,
Sébastien.
