It doesn't seem to 'bite' when invoking a build from a 'seat' using bash or csh
or sh.
Keeping in mind that scripting WITIHIN Makefiles always has its own
specification as to which shell is wanted, I wouldn't expect it to matter.
Unless the sh and csh binaries have been removed or over-written?
If someone can tell me which ports exhibit the alleged problem, I'll try it and
see what happens (no 5.X, but otherwise have 4.11 thru 8-CURRENT ready to hand)..
I will not be surprised if it occurs when building as an 'ordinary user' and
does NOT occur when building as root....
