NAME

     c99 -- standard C language compiler


SYNOPSIS

     c99 [-cEgs] [-D name[=value]] ... [-I directory ...] [-L directory ...]
         [-o outfile] [-O optlevel] [-U name ...] operand ...


DESCRIPTION

     This is the name of the C language compiler as required by the IEEE Std
     1003.1-2001 (``POSIX.1'') standard.

     The c99 compiler accepts the following options:

     -c      Suppress the link-edit phase of the compilation, and do not
             remove any object files that are produced.

     -D name[=value]
             Define name as if by a C-language #define directive.  If no
             ``=value'' is given, a value of 1 will be used.  Note that in
             order to request a translation as specified by IEEE Std
             1003.1-2001 (``POSIX.1''), you need to define
             _POSIX_C_SOURCE=200112L either in the source or using this
             option.  The -D option has lower precedence than the -U option.
             That is, if name is used in both a -U and a -D option, name will
             be undefined regardless of the order of the options.  The -D
             option may be specified more than once.

     -E      Copy C-language source files to the standard output, expanding
             all preprocessor directives; no compilation will be performed.

     -g      Produce symbolic information in the object or executable files.

     -I directory
             Change the algorithm for searching for headers whose names are
             not absolute pathnames to look in the directory named by the
             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 #include
             line, then in directories named in -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 directo-
             ries named in -I options and then in the usual places.  Directo-
             ries named in -I options shall be searched in the order speci-
             fied.  The -I option may be specified more than once.

     -L directory
             Change the algorithm of searching for the libraries named in the
             -l objects to look in the directory named by the directory path-
             name before looking in the usual places.  Directories named in -L
             options will be searched in the order specified.  The -L option
             may be specified more than once.

     -o outfile
             Use the pathname outfile, instead of the default a.out, for the
             executable file produced.

     -O optlevel
             If optlevel is zero, disable all optimizations.  Otherwise,
             enable optimizations at the specified level.

     -s      Produce object and/or executable files from which symbolic and
             other information not required for proper execution has been
             removed (stripped).

     -U name
             Remove any initial definition of name.  The -U option may be
             specified more than once.

     -W 64   Make pointers 64 bits.  There is presently no -W 32 option, since
             it is the default.

     An operand is either in the form of a pathname or the form -l library.
     At least one operand of the pathname form needs to be specified.  Sup-
     ported operands are of the form:

           file.c      A C-language source file to be compiled and optionally
                       linked.  The operand must be of this form if the -c
                       option is used.

           file.a      A library of object files, as produced by ar(1), passed
                       directly to the link editor.

           file.o      An object file produced by c99 -c, and passed directly
                       to the link editor.

           -l library  Search the library named liblibrary.a.  A library will
                       be searched when its name is encountered, so the place-
                       ment of a -l operand is significant.
