An attempt to build out of the source tree from yesterday and run off it
went well except that:

/usr/lib/libc.so.12: Undefined PLT symbol "setsid" (reloc type = 26,
symnum = 1002)

happened, which caused most programs to not be able to run. Is it my
toolchain that is out of date? This is a NetBSD-1.4 or so:

nobble > gcc -v
Using builtin specs.
