Subject: libtool.m4: For MS dumpbin drop CR first.
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=240816b3106f29d5e21139f631f96fa2efc5f3db;p=thirdparty%2Flibtool.git

libtool.m4: For MS dumpbin drop CR first.

On Cygwin, gawk-4.1.4-3 and newer do not treat the input stream as text
any more, leaving us behind with carriage return in symbol names.
* m4/libtool.m4 (lt_cv_sys_global_symbol_pipe): In AWK script for MS
dumpbin drop CR first.
