...ntly yes. not generally, though. [...] > What's *intended* re: openssh? Support for LD=ld or only =gcc, or undef'd ? Well the intent is you should be able to set CC and LD to whatever you want as long as they work. In this case, the OSSH_CHECK_LDFLAG_LINK test invokes autoconf's AC_LINK_IFELSE with uses CC not LD. I'm not sure what to do about it yet though. -- Darren Tucker (dtucker at dtucker.net) GPG key 11EAA6FA / A86E 3E07 5B19 5880 E860 37F4 9357 ECEF 11EA A6FA (new) Good judgement comes with experience.

I don't see a way to get AC_LINK_IFELSE to use $LD rather than $CC, but I think we can prevent this problem by detecting the unsupported option earlier. Please try this diff. It should also prevent the warnings...
