ax_cflags_warn_all

<h2>
SYNOPSIS
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]</code>
</p>
<h2>
DESCRIPTION
</h2>
<div class="indent">
<p>
Try to find a compiler option that enables most reasonable warnings. This
macro is directly derived from <a href=
"vl_prog_cc_warnings.html">VL_PROG_CC_WARNINGS</a> which is split up into
two AX_CFLAGS_WARN_ALL and <a href=
"ax_cflags_warn_all_ansi.html">AX_CFLAGS_WARN_ALL_ANSI</a>
</p>
<p>
For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The result
is added to the shellvar being CFLAGS by default.
</p>
<p>
Currently this macro knows about GCC, Solaris C compiler, Digital Unix C
compiler, C for AIX Compiler, HP-UX C compiler, IRIX C compiler, NEC SX-5
(Super-UX 10) C compiler, and Cray J90 (Unicos 10.0.0.8) C compiler.
</p>
<pre>
- $1 shell-variable-to-add-to : CFLAGS
- $2 add-value-if-not-found : nothing
- $3 action-if-found : add value to shellvariable
- $4 action-if-not-found : nothing
</pre>
