fix aclocal.m4's main prototype

aclocal.m4 uses "int main(int argc, char *argv[]" as the prototype for main for
various tests. However, the [] isn't quoted/escaped/whatever properly and is
discarded by autotools, leaving "int main(int argc, char *argv" in configure.

clang treats this invalid main prototype as a hard error, so these configure
tests fail.

Attached patch fixes it.
