# 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.
# Rely on autoconf to set up CDPATH properly.

dnl RTEMS_BSPOPTS_* - some autoconf voodoo to handle default values and
dnl help-strings for per-BSP-environment variables.
dnl To be used in bsp-configure scripts
dnl Example:
dnl
dnl RTEMS_BSPOPTS_SET([foo],[bar],[0])
dnl RTEMS_BSPOPTS_SET([foo],[baz*],[hello])
dnl RTEMS_BSPOPTS_SET([foo],[*],[])
dnl RTEMS_BSPOPTS_HELP([foo],[env. variable foo])
dnl -> Add "0" as default value of variable "foo" for BSP "bar"
dnl -> Add "hello" as default value of variable "foo" for all BSPs starting
dnl with "baz" in their name.
dnl -> Undefine foo as default clause for all BSP's.
dnl
dnl All this basically expands to a /bin/shell "case"-statement with
dnl accompanying autoconf magic to propagate VAR to bspopts.h.
dnl RTEMS_BSPOPTS_HELP(VAR,HELP-STRING)
dnl Set up printing the HELP-STRING for bspopts.h's variable VAR and add
dnl appropriate /bin/sh-magic to "configure" to have VAR set up.

dnl RTEMS_BSPOPTS_SET(VAR,BSP,DEFAULT)
dnl Set up a value DEFAULT to be used as default value for variable VAR for
dnl BSP in RTEMS_BSPOPTS_HELP.
dnl MUST be use in front of exactly _one_ corresponding RTEMS_BSPOPTS_HELP

dnl RTEMS_ARG_VAR(VAR,HELP-STRING)
