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. |
