# The following should look at the current guess and probe the system to
# establish a better guess in exact_cpu. Leave exact_cpu empty if probes
# can't be done, or don't work.
#
# When a number of probes are done, test -z "$exact_cpu" can be used instead
# of putting each probe under an "else" of the preceeding. That can stop
# the code getting horribly nested and marching off the right side of the
# screen.
# Note that when a compile-and-link is done in one step we need to remove .o
# files, since lame C compilers generate these even when not asked.
#
# CC_FOR_BUILD -- compiler used by this script. Note that the use of a
# compiler to aid in system detection is discouraged as it requires
# temporary files to be created and, as you can see below, it is a
# headache to deal with in a portable fashion.
# Historically, `CC_FOR_BUILD' used to be named `HOST_CC'. We still
# use `HOST_CC' if defined, but it is deprecated.
# Portable tmp directory creation inspired by the Autoconf team.
