25?X: This unit ends up producing the config.sh script, which contains all the
26?X: definitions figured out by Configure. The add.Config_sh command knows
27?X: which variables need to be remembered. It also adds the EOT (ends the
28?X: here document redirection with variable substitution).

66?X: Strip down paths in located executables. For each file, e.g. vi, there

74?X:
75?X: Previously, we used to do eval $file="\$file" but in order
76?X: to handle things like sh Configure -Dmake=gmake, we can't do
77?X: that. What we *really* want is to strip away the absolute path
78?X: and rely on the end user's $PATH to correctly find the executable.
79?X: This method assumes there is a "basename" command available. If
80?X: not, replace it with the following expr-based command:
81?X: expr $temp : '.*/\(.*\)' \| $temp
9b04e79a 82?X: Since this preserves the actual command name, we can now drop the

JH
86?X: On OS/2, a special $ar command not even named 'ar' is required,
87?X: so we don't strip that name.
88?X: Also, on DOSish systems, there might not be a ln command, but we
89?X: might have ln='cp'.
90?X: However, we can't set d_portable=undef on such systems since
91?X: Unix-ish tools don't have standard locations there. Thus we
92?X: MUST rely on the user's $PATH.
