-- Macro: AC_CHECK_TOOL (VARIABLE, PROG-TO-CHECK-FOR,
[VALUE-IF-NOT-FOUND], [PATH])
Like `AC_CHECK_PROG', but first looks for PROG-TO-CHECK-FOR with a
prefix of the host type as determined by `AC_CANONICAL_HOST',
followed by a dash (*note Canonicalizing::). For example, if the
user runs `configure --host=i386-gnu', then this call:
AC_CHECK_TOOL([RANLIB], [ranlib], [:])
sets `RANLIB' to `i386-gnu-ranlib' if that program exists in
`PATH', or otherwise to `ranlib' if that program exists in `PATH',
or to `:' if neither program exists.
In the future, when cross-compiling this macro will _only_ accept
program names that are prefixed with the host type. For more
information, see *Note Specifying the system type: Specifying
Names.
Perfect! You've shown me two things -- how this macro works, and how
to use "info" without pulling my hair out. Thanks again!
