Hi,
It appears that AC_PATH_PROG has changed behaviour between 2.13 and 2.5x.
If the following configure.in file is processed with autoconf 2.13,
all three calls correctly find "ls"
AC_INIT
AC_PATH_PROG(LS1,ls,no)
echo "LS=$LS1"
AC_PATH_PROG(LS2,ls,no,$PATH)
echo "LS=$LS2"
AC_PATH_PROG(LS3,ls,no,"$PATH")
echo "LS=$LS3"
AC_OUTPUT
However, if processed with autoconf 2.53 or 2.53a (CVS as of yesterday)
the last call (with quoted "$PATH") fails.
steve@riemann{ac-path-prog}/usr/local/experimental/bin/autoconf
steve@riemann{ac-path-prog}./configure
checking for ls... /bin/ls
LS=/bin/ls
checking for ls... /bin/ls
LS=/bin/ls
checking for ls... no
LS=no
I was a bit surprised by this. Bug or feature?
