Subject: libtool: allow tabs in *_cmds variables
X-Git-Tag: v2.4.2.418~55
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=726bf31ced115a9c21470c340ef7fda2f2992544;p=thirdparty%2Flibtool.git

libtool: allow tabs in *_cmds variables

This is in preparation for the next patch, which needs to have literal
tab characters survive the evaluation of the *_cmds variables.

build-aux/ltmain.in (func_execute_cmds, func_mode_link): Don't collapse
tabs and surrounding whitespace into a single space when executing a
tilde-separated cmds construct, instead keep any tabs intact.
