Subject: Hack canonicalize_file_name (should be fixed in gnulib)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8e274eb3d98d71302c5a82037a4fef9422162c12;p=thirdparty%2Fbinutils-gdb.git

Hack canonicalize_file_name (should be fixed in gnulib)

Needed when cross compiling.

The gnulib canonicalize_file_name override breaks finding cygwin1.dll.

When compiling natively, gnulib doesn't override
canonicalize_file_name, but gnulib has hardcoded defaults for cross
compiling, and the default is wrong for Cygwin.
