Unifdef isn't used anymore --- it was only used with Imake. Removing it,

to make the distribution (marginally) smaller.

-.Dd April 23, 1991
-.Dt UNIFDEF 1
-.Os BSD 4.3
-.Sh NAME
-.Nm unifdef
-.Nd remove ifdef'ed lines
-.Sh SYNOPSIS
-.Nm unifdef
-.Oo
-.Fl t l c
-.Fl D Ns Ar sym
-.Fl U Ns Ar sym
-.Fl iD Ns Ar sym
-.Fl iD Ns Ar sym
-.Oc
-.Ar ...
-.Op Ar file
-.Sh DESCRIPTION
-.Nm Unifdef
-is useful for removing ifdef'ed lines
-from a file while otherwise leaving the file alone.
-.Nm Unifdef
-acts on
-#ifdef, #ifndef, #else, and #endif lines,
-and it knows only enough about C
-to know when one of these is inactive
-because it is inside
-a comment,
-or a single or double quote.
-Parsing for quotes is very simplistic:
-when it finds an open quote,
-it ignores everything (except escaped quotes)
-until it finds a close quote, and
-it will not complain if it gets
-to the end of a line and finds no backslash for continuation.
-.Pp
-Available options:
-.Bl -tag -width Ds -compact
-.It Fl D Ns Ar sym
-.It Fl U Ns Ar sym
-Specify which symbols to define or undefine.
-and the lines inside those ifdefs will be copied to the output or removed as
-appropriate.
-The ifdef, ifndef, else, and endif lines associated with
-.Ar sym
-will also be removed.
-Ifdefs involving symbols you don't specify
-and ``#if'' control lines
-are untouched and copied out
-along with their associated
-ifdef, else, and endif lines.
-If an ifdef X occurs nested inside another ifdef X, then the
-inside ifdef is treated as if it were an unrecognized symbol.
-If the same symbol appears in more than one argument,
-the last occurrence dominates.
-.Pp
-.It Fl c
-If the
-.Fl c
-flag is specified,
-then the operation of
-.Nm unifdef
-is complemented,
-i.e. the lines that would have been removed or blanked
-are retained and vice versa.
-.Pp
-.It Fl l
-Replace removed lines with blank lines
-instead of deleting them.
-.It Fl t
-Disables parsing for
-C comments and quotes useful for plain text
-(not C code).
-.Pp
-.It Fl iD Ns Ar sym
-.It Fl iU Ns Ar sym
-Ignore ifdefs.
-If your C code uses ifdefs to delimit non-C lines,
-such as comments
-or code which is under construction,
-then you must tell
-.Nm unifdef
-which symbols are used for that purpose so that it won't try to parse
-for quotes and comments
-inside those ifdefs.
-One specifies ignored ifdefs with
-.Fl iD Ns Ar sym
-and
-.Fl iU Ns Ar sym
-similar to
-.Fl D Ns Ar sym
-and
-.Fl U Ns Ar sym
-above.
-.El
-.Pp
-.Nm Unifdef
-copies its output to
-.Em stdout
-and will take its input from
-.Em stdin
-if no
-.Ar file
-argument is given.
-.Pp
-.Nm Unifdef
-works nicely with the
-.Fl D Ns Ar sym
-option added to
-.Xr diff 1
-as of the 4.1 Berkeley Software Distribution.
-.Sh SEE ALSO
-.Xr diff 1
-.Sh DIAGNOSTICS
-Inappropriate else or endif.
-.br
-Premature
-.Tn EOF
-with line numbers of the unterminated #ifdefs.
-.Pp
-Exit status is 0 if output is exact copy of input, 1 if not, 2 if trouble.
-.Sh BUGS
-Should try to deal with ``#if'' lines.
-.Pp
-Doesn't work correctly if input contains null characters.
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.3 .
