+#define	HISTFRACTION	2
+
+/* Fraction of text space to allocate for from hash buckets.
+   The value of HASHFRACTION is based on the minimum number of bytes
+   of separation between two subroutine call points in the object code.
+   Given MIN_SUBR_SEPARATION bytes of separation the value of
+   HASHFRACTION is calculated as:
+  
+  	HASHFRACTION = MIN_SUBR_SEPARATION / (2 * sizeof (short) - 1);
+  
+   For example, on the VAX, the shortest two call sequence is:
+  
+  	calls	$0,(r0)
+  	calls	$0,(r0)
+  
+   which is separated by only three bytes, thus HASHFRACTION is
+   calculated as:
+  
+  	HASHFRACTION = 3 / (2 * 2 - 1) = 1
+  
+   Note that the division above rounds down, thus if MIN_SUBR_FRACTION
+   is less than three, this algorithm will not work!
+  
+   In practice, however, call instructions are rarely at a minimal
+   distance.  Hence, we will define HASHFRACTION to be 2 across all
+   architectures.  This saves a reasonable amount of space for
+   profiling data structures without (in practice) sacrificing

+   Profiling a test case with 64000 small functions will work if

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.
