This guy looks good to me. Any objection?

Hello!
"ACLOCAL_AMFLAGS = -I ." causes circular dependencies. The patch fixes
this problem, eliminates an extra occurence of acinclude.m4 and strips
"./" from the remaining macro files in "."
A test for the above patch is also provided.
Regards,
Pavel Roskin
