# 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
