It turns out that their version of make 3.82 is only partially patched. The specific check we look for looks for two different problems. The first is a target that includes target(dep1 dep2 dep3). The second is a target that starts with leading spaces. From what I can tell, most Fedora 3.82 versions are patched for the first problem, but not the second. There are other problems with 3.82, but this patch appears to detect the most broken of 3.82 versions in common use. (And no, this is no longer an RFC. I think this is the correct patch!) --Mark On 6/18/13 3:17 PM, Mark Hatle wrote: > See GNU Savannah bug 30612 -- make 3.82 is known to be broken. > > A number of vendors are providing a modified version, so checking > for just the version string is not enough.
