I work with Poky (pokylinux.org) and OpenEmbedded (openembedded.org) which are cross compiling build systems and speed improvements like this are extremely useful to us. Those systems also provide a testing ground where we can expose changes like this to a wide variety of programs. My main problem is this change is that the last part doesn't hold true, dolt does not fall back to libtool transparently, the reason being the AC_SUBST causes LTCOMPILE to become "", even if that section of the if block isn't called. I've just hacked dolt into Poky's libtool recipes and will have the build time differences from our automated builds in about 24 hours provided nothing breaks and I'll report back.
