# This file defines new macros to process configure command line
|
|
# arguments, to replace the brain-dead AC_ARG_WITH and AC_ARG_ENABLE.
|
|
# The flaw in these is particularly that they only differentiate
|
|
# between "given" and "not given" and do not provide enough help to
|
|
# process arguments that only accept "yes/no", that require an
|
|
# argument (other than "yes/no"), etc.
|
|
#
|
|
# The point of this implementation is to reduce code size and
|
|
# redundancy in configure.in and to improve robustness and consistency
|
|
# in the option evaluation code.
|
|
|
|
|
|
# Convert type and name to shell variable name (e.g., "enable_long_strings")

# This is the base layer. TYPE is either "with" or "enable", depending

# on what you like. NAME is the rest of the option name, HELP-STRING
|
|
# as usual. ACTION-IF-YES is executed if the option is given without
|
|
# an argument (or "yes", which is the same); similar for ACTION-IF-NO.
