>Description:
FreeBSD is missing the P1003.1-2001 c99 utility.
>How-To-Repeat:
c99 foo.c
>Fix:
Here is an implementation of the c99 utility. The manual page is based
on Joerg Wunsch's page for c89.
It's pretty much trivial, the only interesting thing it does is in
addlib(), where it maps -lpthread to the -pthread gcc option, and
removes -lxnet and -lrt because they are not available on FreeBSD,
their functionality is in libc.

X.Sh NAME
X.Nm c99
X.Nd standard C language compiler
X.Sh SYNOPSIS
X.Nm
X.Op Fl cEgs
X.Op Fl D Ar name Ns Op = Ns Ar value
X.Ar ...
X.Op Fl I Ar directory ...
X.Op Fl L Ar directory ...
X.Op Fl o Ar outfile
X.Op Fl O Ar optlevel
X.Op Fl U Ar name ...
X.Ar operand ...
X.Sh DESCRIPTION
XThis is the name of the C language compiler as required by the
X.St -p1003.1-2001
Xstandard.
X.Pp
XThe
X.Nm
Xcompiler accepts the following options:
X.Bl -tag -width indent
X.It Fl c
XSuppress the link-edit phase of the compilation, and do not remove any
Xobject files that are produced.
X.It Fl D Ar name Ns Op = Ns Ar value
XDefine name as if by a C-language
X.Ic #define
Xdirective. If
Xno
X.Dq = Ns Ar value
Xis given, a value of 1 will be used.
XThe
X.Fl D
Xoption has lower precedence than the
X.Fl U
Xoption. That is, if
X.Ar name
Xis used in both a
X.Fl U
Xand a
X.Fl D
Xoption,
X.Ar name
Xwill be undefined regardless of the order of the options. The
X.Fl D
Xoption may be specified more than once.
X.It Fl E
XCopy C-language source files to the standard output, expanding all
Xpreprocessor directives; no compilation will be performed.
X.It Fl g
XProduce symbolic information in the object or executable files.
X.It Fl I Ar directory
XChange the algorithm for searching for headers whose names are not
Xabsolute pathnames to look in the directory named by the
X.Ar directory
Xpathname before looking in the usual places. Thus, headers whose
Xnames are enclosed in double-quotes ("") will be searched for first
Xin the directory of the file with the
X.Ic #include
Xline, then in
Xdirectories named in
X.Fl I
Xoptions, and last in the usual places. For
Xheaders whose names are enclosed in angle brackets (<>), the header
Xwill be searched for only in directories named in
X.Fl I
Xoptions and then in the usual places. Directories named in
X.Fl I
Xoptions shall be searched in the order specified. The
X.Fl I
Xoption may be specified more than once.
X.It Fl L Ar directory
XChange the algorithm of searching for the libraries named in the
X.Fl l
Xobjects to look in the directory named by the
X.Ar directory
Xpathname before looking in the usual places. Directories named in
X.Fl L
Xoptions will be searched in the order specified. The
X.Fl L
Xoption may be specified more than once.
X.It Fl o Ar outfile
XUse the pathname
X.Ar outfile ,
Xinstead of the default
X.Pa a.out ,
Xfor the executable file produced.
X.It Fl O Ar optlevel
XIf
X.Ar optlevel
Xis zero, disable all optimizations. Otherwise, enable optimizations at
Xthe specified level.
X.It Fl s
XProduce object and/or executable files from which symbolic and other
Xinformation not required for proper execution has been removed
X(stripped).
X.It Fl U Ar name
XRemove any initial definition of
X.Ar name .
XThe
X.Fl U
Xoption may be specified more than once.
X.El
X.Pp
XAn operand is either in the form of a pathname or the form
X.Fl l
Xlibrary. At least one operand of the pathname form needs to be
Xspecified. Supported operands are of the form:
X.Bl -tag -offset indent -width "-l library"
X.It Ar file Ns Pa .c
XA C-language source file to be compiled and optionally linked. The
Xoperand must be of this form if the
X.Fl c
Xoption is used.
X.It Ar file Ns Pa .a
XA library of object files, as produced by
X.Xr ar 1 ,
Xpassed directly to the link editor.
X.It Ar file Ns Pa .o
XAn object file produced by
X.Nm Fl c ,
Xand passed directly to the link editor.
X.It Fl l Ar library
XSearch the library named
X.Pa lib Ns Ar library Ns Pa .a .
XA library will be searched when its name is encountered, so the
Xplacement of a
X.Fl l
Xoperand is significant.

X.Sh STANDARDS
XThe
X.Nm
Xcommand is believed to comply with
X.St -p1003.1-2001 .
X.Sh BUGS
XThe standard
X.Pa trace
Xlibrary does not exist in
X.Fx
Xso
X.Fl l Pa trace
Xdoes not work.
