unittest:

  rename *.t* to *-t* to be automake-friendly
  simplify Makefiles
test_atomic.c:
  move to unittest, add GPL comment, fix warnings, convert to tap framework.
configure:
  remove custom tests for available types, use AC_CHECK_TYPE instead
x86-gcc.h:
  fix gcc -ansi errors while maintaining readability
ignore:
  added *-t
