dnldnl Borrowed (and altered) from Bill Gropp's confdb PAC_PROG_CHECK_INSTALL_WORKS.dnldnl Fixes to bugs in AC_xxx macrosdnl dnl MPD_AC_PROG_CHECK_INSTALL_WORKS - Check whether the install program in INSTALLdnl works.dnldnl Synopsis:dnl MPD_AC_PROG_CHECK_INSTALL_WORKSdnldnl Output Effect:dnl   Sets the variable 'INSTALL' to the value of 'ac_sh_install' if dnl   a file cannot be installed into a local directory with the 'INSTALL'dnl   programdnldnl Notes:dnl   The 'AC_PROG_INSTALL' scripts tries to avoid broken versions of dnl   install by avoiding directories such as '/usr/sbin' where some dnl   systems are known to have bad versions of 'install'.  Unfortunately, dnl   this is exactly the sort of test-on-name instead of test-on-capabilitydnl   that 'autoconf' is meant to eliminate.  The test in this scriptdnl   is very simple but has been adequate for working around problems dnl   on Solaris, where the '/usr/sbin/install' program (known by dnl   autoconf to be bad because it is in /usr/sbin) is also reached by a dnl   soft link through /bin, which autoconf believes is good.dnldnl   No variables are cached to ensure that we do not make a mistake in dnl   our choice of install program.dnlAC_DEFUN([MPD_AC_PROG_CHECK_INSTALL_WORKS],[# Check that this install really worksrm -f conftestecho "Test file" > conftestif test ! -d .conftest ; then mkdir .conftest ; fiAC_MSG_CHECKING([whether install $INSTALL works])if $INSTALL -m 644 conftest .conftest >/dev/null 2>&1 ; then    installOk=yeselse    installOk=nofirm -rf .conftest conftestAC_MSG_RESULT($installOk)dnl if test "$installOk" = no ; then    dnl AC_MSG_ERROR([Unable to find working install])dnl fidnl installOk=no  # RMB DEBUG])
