Not to be blunt or anything but the list of autoconf macros is at
<http://www.gnu.org/software/autoconf/manual/html_node/Autoconf-Macro-Index.html>
and it's simple to ctrl-f that page.

Maybe you should explain why you're asking, since tcl already has a
perfectly reasonable test:

AC_CACHE_CHECK(for SEH support in compiler,
    tcl_cv_seh,
AC_TRY_RUN([
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#undef WIN32_LEAN_AND_MEAN

int main(int argc, char** argv) {
    int a, b = 0;
    __try {
        a = 666 / b;
    }
    __except (EXCEPTION_EXECUTE_HANDLER) {
        return 0;
    }
    return 1;
}
],
        tcl_cv_seh=yes,
        tcl_cv_seh=no,
        tcl_cv_seh=no)
)
if test "$tcl_cv_seh" = "no" ; then
    AC_DEFINE(HAVE_NO_SEH, 1,
            [Defined when mingw does not support SEH])
fi
