# SYNOPSIS
|
|
#
|
|
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Try to find a compiler option that enables most reasonable warnings.
|
|
#
|
|
# 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

dnl implementation tactics:
|
|
dnl the for-argument contains a list of options. The first part of
|
|
dnl these does only exist to detect the compiler - usually it is
|
|
dnl a global option to enable -ansi or -extrawarnings. All other
|
|
dnl compilers will fail about it. That was needed since a lot of
|
|
dnl compilers will give false positives for some option-syntax
|
|
dnl like -Woption or -Xoption as they think of it is a pass-through
|
|
dnl to later compile stages or something. The "%" is used as a
|
|
dnl delimimiter. A non-option comment can be given after "%%" marks
|
|
dnl which will be shown but not added to the respective C/CXXFLAGS.
