NAME
     c89 — ANSI (1989) C compiler

SYNOPSIS
     c89 [-pedantic] [-pedantic-errors] [-D_ANSI_SOURCE] [options ...]

DESCRIPTION
     Calls the C compiler (cc) with the given options, using a C language
     environment compatible with the ANSI X3.159-1989 (“ANSI C89”) specifica‐
     tion.

     This includes proper handling of trigraphs, disabling non-ANSI compiler
     features (such as asm, inline, typeof, and the $ character in identi‐
     fiers), and definition of the preprocessor symbol __STRICT_ANSI__.

     The following options are available:

     -pedantic		 Issue extra warnings defined by ANSI for use of non-
			 ANSI features.

     -pedantic-errors	 Issue errors instead of warnings that normally would
			 be presented by -pedantic.

     -D_ANSI_SOURCE	 Tell the system header file set to use an ANSI-con‐
			 formant "clean" namespace.

SEE ALSO
     cc(1)

STANDARDS
     c89 conforms to IEEE Std 1003.2-1992 (“POSIX.2”).

HISTORY
     c89 appeared in NetBSD 1.4.

BUGS
     Since c89 is a shell wrapper script to cc, compile errors are prefixed by
     "cc:".
