# SYNOPSIS
|
|
#
|
|
# AX_CFLAGS_WARN_ALL_ANSI [(shellvar [,default, [A/NA]])]
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Try to find a compiler option that enables most reasonable
|
|
# warnings. This macro is directly derived from VL_PROG_CC_WARNINGS
|
|
# which is split up into two AX_CFLAGS_WARN_ALL and
|
|
# AX_CFLAGS_WARN_ALL_ANSI
|
|
#
|
|
# For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The
|
|
# result is added to the shellvar being CFLAGS by default.
|
|
#
|
|
# 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.
|
|
#
|
|
# - $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
