+#
+# SYNOPSIS
+#
+# AX_CFLAGS_STRICT_PROTOTYPES [(shellvar [,default, [A/NA]]
+#
+# DESCRIPTION
+#
+# Try to find a compiler option that requires strict prototypes.
+#
+# The sanity check is done by looking at sys/signal.h which has a set
+# of macro-definitions SIG_DFL and SIG_IGN that are cast to the local
+# signal-handler type. If that signal-handler type is not fully
+# qualified then the system headers are not seen as strictly
+# prototype clean.
+#
+# For the GNU CC compiler it will be -fstrict-prototypes
+# -Wstrict-prototypes The result is added to the shellvar being
+# CFLAGS by default.
+#
+# DEFAULTS:
+#
+# - $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

+# AX_CFLAGS_WARN_ALL [(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

+#
+# For the GNU CC compiler it will be -Wall (and -ansi -pedantic) The

+#
+# 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.

+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.
