Importing flex 2.6.4 has introduced a regression: input() now returns 0
instead of EOF to indicate that the end of input was reached, just like
traditional AT&T and POSIX lex. Note the behavior contradicts flex(1).
See "INCOMPATIBILITIES WITH LEX AND POSIX" section for information.
This incompatibility traces back to the original version and documented
in its manual page by the Vern Paxson.
Apparently, it has been reported in a few places, e.g.,
https://github.com/westes/flex/issues/448
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911415
Unfortunately, this also breaks the scanner used by libdtrace and
dtrace is unable to resolve some probe argument types as a result. See
PR253440 for more information.
Note the regression was introduced by the following upstream commit
without any explanation or documentation change:

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
