|

dnl
|
|
dnl Test for --enable-${FEATURE_NAME} and set to DEFAULT_VAL value if feature not specified.
|
|
dnl Also calls AC_DEFINE to define HAVE_${HAVE_NAME} if value is not equal to "no"
|
|
dnl
|
|
dnl Use this macro to facilitate definition of options in a package. For example:
|
|
dnl
|
|
dnl TAC_ARG_ENABLE_OPTION(threads, [enable shared memory threads], THREADS, no)
|
|
dnl
|
|
dnl will test for --enable-threads when configure is run. If it is defined (and not set to "no")
|
|
dnl then HAVE_THREADS will be defined, Otherwise HAVE_THREADS will not be defined.
