I have seen a problem with building wget 1.7 on solaris 8. The build hangs. According to POSIX, X/Open and many implementations of make, $< is only meaningful in inference rules and not target rules. In the case of solaris (/usr/ccs/bin/make) substitutes the empty string for the $< macro, so the sed command waits for input from stdin which it never receives, hence the hang.
In the interest of portability I suggest changing the target rules to use the actual value of the target name where $< is currently being used. Thanks in advance Joe Townsend
