Add the c99(1) utility, which is nothing more than a synonym for

cc -std=iso9899:1999 -pedantic, and is required by SUSv3.

+.Sh NAME
+.Nm c99
+.Nd standard C language compiler
+.Sh SYNOPSIS
+.Nm
+.Op Fl cEgs
+.Op Fl D Ar name Ns Op = Ns Ar value
+.Ar ...
+.Op Fl I Ar directory ...
+.Op Fl L Ar directory ...
+.Op Fl o Ar outfile
+.Op Fl O Ar optlevel
+.Op Fl U Ar name ...
+.Ar operand ...
+.Sh DESCRIPTION
+This is the name of the C language compiler as required by the
+.St -p1003.1-2001
+standard.
+.Pp
+The
+.Nm
+compiler accepts the following options:
+.Bl -tag -width indent
+.It Fl c
+Suppress the link-edit phase of the compilation, and do not remove any
+object files that are produced.
+.It Fl D Ar name Ns Op = Ns Ar value
+Define name as if by a C-language
+.Ic #define
+directive.  If
+no
+.Dq = Ns Ar value
+is given, a value of 1 will be used.
+Note that in order to request a
+translation as specified by
+.St -p1003.1-2001
+you need to define
+.Dv _POSIX_C_SOURCE=200112L
+either in the source or using this option.  The
+.Fl D
+option has lower precedence than the
+.Fl U
+option.  That is, if
+.Ar name
+is used in both a
+.Fl U
+and a
+.Fl D
+option,
+.Ar name
+will be undefined regardless of the order of the options.  The
+.Fl D
+option may be specified more than once.
+.It Fl E
+Copy C-language source files to the standard output, expanding all
+preprocessor directives; no compilation will be performed.
+.It Fl g
+Produce symbolic information in the object or executable files.
+.It Fl I Ar directory
+Change the algorithm for searching for headers whose names are not
+absolute pathnames to look in the directory named by the
+.Ar directory
+pathname before looking in the usual places.  Thus, headers whose
+names are enclosed in double-quotes ("") will be searched for first
+in the directory of the file with the
+.Ic #include
+line, then in
+directories named in
+.Fl I
+options, and last in the usual places.  For
+headers whose names are enclosed in angle brackets (<>), the header
+will be searched for only in directories named in
+.Fl I
+options and then in the usual places.  Directories named in
+.Fl I
+options shall be searched in the order specified.  The
+.Fl I
+option may be specified more than once.
+.It Fl L Ar directory
+Change the algorithm of searching for the libraries named in the
+.Fl l
+objects to look in the directory named by the
+.Ar directory
+pathname before looking in the usual places.  Directories named in
+.Fl L
+options will be searched in the order specified.  The
+.Fl L
+option may be specified more than once.
+.It Fl o Ar outfile
+Use the pathname
+.Ar outfile ,
+instead of the default
+.Pa a.out ,
+for the executable file produced.
+.It Fl O Ar optlevel
+If
+.Ar optlevel
+is zero, disable all optimizations. Otherwise, enable optimizations at
+the specified level.
+.It Fl s
+Produce object and/or executable files from which symbolic and other
+information not required for proper execution has been removed
+(stripped).
+.It Fl U Ar name
+Remove any initial definition of
+.Ar name .
+The
+.Fl U
+option may be specified more than once.
+.El
+.Pp
+An operand is either in the form of a pathname or the form
+.Fl l
+library.  At least one operand of the pathname form needs to be
+specified.  Supported operands are of the form:
+.Bl -tag -offset indent -width "-l library"
+.It Ar file Ns Pa .c
+A C-language source file to be compiled and optionally linked.  The
+operand must be of this form if the
+.Fl c
+option is used.
+.It Ar file Ns Pa .a
+A library of object files, as produced by
+.Xr ar 1 ,
+passed directly to the link editor.
+.It Ar file Ns Pa .o
+An object file produced by
+.Nm Fl c ,
+and passed directly to the link editor.
+.It Fl l Ar library
+Search the library named
+.Pa lib Ns Ar library Ns Pa .a .
+A library will be searched when its name is encountered, so the
+placement of a
+.Fl l
+operand is significant.
+.El
+.Sh SEE ALSO
+.Xr ar 1 ,
+.Xr c89 1 ,
+.Xr cc 1
+.Sh STANDARDS
+The
+.Nm
+utility interface conforms to
+.St -p1003.1-2001 .
+Since it is a wrapper around
+.Tn GCC ,
+it is limited to the C99 features that GCC actually implements.
+See
+.Em http://gcc.gnu.org/gcc-3.1/c99status.html .
