Oh, now I remember!
The problem is that we don't have an acconfig.h template since we
moved all define templates into the third argument of AC_DEFINE.
However, AC_CHECK_TYPE calls AC_DEFINE without such an argument, so
autoheader would complain about no template being available for
ssize_t. This was the ugly work-around I had come up with.
