# 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”) specification.

This includes proper handling of trigraphs, disabling non-ANSI compiler features (such as asm, inline, typeof, and the $ character in identifiers), 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-conformant "clean" namespace.

# STANDARDS

# HISTORY

`c89` appeared in NetBSD 1.4.

# BUGS

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