libc breaks lex
Apparently something in the new locale code in libc is breaking lex. This prevents a full nightly from completing. Indeed, its most easily seen when trying to build the cscope_fast program under usr/src/tools.
Its amazing that other programs don't seem to be broken. This needs to be fixed urgently.

So the problem here appears to be _scrwidth(). For non-printable characters, the current implementation returns -1, which confuses fprintf() when %ws is used. In such cases 0 should be returned.
While here, I noticed that a bunch of cstyle test macros used !! to return 1 for true instead of a real bit value, and testing shows that the legacy code returns the actual bit value. We need to fix that here.
