Subject: Add a copy of dolt.m4 to acinclude.m4.
X-Git-Tag: 2.5.93~10
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=4dfb4aa1d4e1a3195d6f2f6873cb48d1d739a1bd;p=fontconfig.git

Add a copy of dolt.m4 to acinclude.m4.

An ancient version of dolt.m4 was installed on my system leading to a broken
build on non-Linux systems.
