# mozconfig2configure - Loads options from .mozconfig onto configure's
# command-line. See mozconfig-find for how the config file is
# found
#
# The options from .mozconfig are inserted into the command-line
# before the real command-line options. This way the real options
# will override any .mozconfig options.
#
# .mozconfig is a shell script. To add an option to configure's
# command-line use the pre-defined function, ac_add_options,
#
# ac_add_options <configure-option> [<configure-option> ... ]
#
# For example,
#
# ac_add_options --with-pthreads --enable-debug
#
# ac_add_options can be called multiple times in .mozconfig.
# Each call adds more options to configure's command-line.
# Note: $_AUTOCONF_TOOLS_DIR must be defined in the script that includes this.
ac_add_options() {
for _opt
do
# Escape shell characters, space, tab, dollar, quote, backslash, parentheses.
_opt=`echo $_opt | sed -e 's/\([\ \ \$\"\\\(\)]\)/\\\\\1/g;s/@\([^@]*\)@/\$\1/g;'`
_opt=`echo $_opt | sed -e 's/@\([^@]*\)@/\$(\1)/g'`
# Avoid adding duplicates
case "$ac_options" in
# Note that all options in $ac_options are enclosed in quotes,
# so there will always be a last character to match [^-A-Za-z0-9_]
