| dnl of some commands and utilities needed to allow
 | |
| dnl configure script bootstrapping itself when using

 | |
| dnl and sets its value unless it is already set with
 | |
| dnl a non-empty value.
 | |
| dnl
 | |
| dnl These basic checks are intended to be placed and
 | |
| dnl executed as early as possible in the resulting
 | |
| dnl configure script, and as such these must be pure
 | |
| dnl and portable shell code.
 | |
| dnl
 | |
| dnl This macro may be used directly, or indirectly
 | |
| dnl when using other macros that AC_REQUIRE it such
 | |
| dnl as XC_CHECK_PATH_SEPARATOR.
 | |
| dnl
 | |
| dnl Currently the mechanism used to ensure that this
 | |
| dnl macro expands early enough in generated configure
 | |
| dnl script is making it override autoconf and libtool
 | |
| dnl PATH_SEPARATOR check.

| dnl XC_CHECK_PATH_SEPARATOR
 | |
| dnl -------------------------------------------------
 | |
| dnl Public macro.
 | |
| dnl
 | |
| dnl Usage of this macro ensures that generated configure
 | |
| dnl script uses the same PATH_SEPARATOR check irrespective
 | |
| dnl of autoconf or libtool version being used to generate
 | |
| dnl configure script.
 | |
| dnl
 | |
| dnl Emits shell code that computes the path separator
 | |
| dnl and stores the result in 'PATH_SEPARATOR', unless
 | |
| dnl the user has already set it with a non-empty value.
 | |
| dnl
 | |
| dnl This path separator is the symbol used to separate
 | |
| dnl or diferentiate paths inside the 'PATH' environment
 | |
| dnl variable.
 | |
| dnl
 | |
| dnl Non-empty user provided 'PATH_SEPARATOR' always
 | |
| dnl overrides the auto-detected one.
 | |
| dnl
 | |
| dnl Strictly speaking the check is done in two steps. The
 | |
| dnl first, which does the actual check, takes place in
 | |
| dnl XC_CONFIGURE_PREAMBLE macro and happens very early in
 | |
| dnl generated configure script. The second one shows and
 | |
| dnl logs the result of the check into config.log at a later
 | |
| dnl configure stage. Placement of this second stage in
 | |
| dnl generated configure script will be done where first
 | |
| dnl direct or indirect usage of this macro happens.
