Does the following work: AC_CHECK_PROGS(FOO1, ["tcc -b" gcc cc]) AC_CHECK_PROGS(FOO2, [tcc gcc cc]) Two things came to my mind: 1) Perhaps you are calling AC_PROG_CC(["tcc -b" gcc cc]) too late. Add "echo $CC" just before it, to make sure that CC is not set yet. Try placing AC_PROG_CC just after AM_INIT_AUTOMAKE or even just after AC_INIT. 2) If you are on a Windows platform and you actually want to find tcc.exe or even tcc.com than you might need $ac_executable_extensions that should normally be set in your config.site. I'm afraid you'll have to debug that part of ./configure yourself.
