+ <code>AX_CFLAGS_WARN_ALL_ANSI [(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 <a href="ax_cflags_warn_all.html">AX_CFLAGS_WARN_ALL</a> and
+ AX_CFLAGS_WARN_ALL_ANSI
+ </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
