Subject: * acx.m4: Name cache variables properly.
X-Git-Tag: cagney-unwind-20030108-branchpoint~60
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=c991d310316fa22039f7889c88917f3e2770df80;p=newlib-cygwin.git

* acx.m4: Name cache variables properly.
(NCN_STRICT_CHECK_TOOL): If program is not found and
value-if-not-found is empty, use ${ncn_tool_prefix}$2 or $2,
depending on whether build != host or not.
(NCN_STRICT_CHECK_TARGET_TOOL): Ditto, with the target prefix.
