Update ax_pkg_swig.m4 and ax_pthread.m4
Use vanilla m4 files with known source. Prepared for possible removal at build time if the system already has autoconf-archive source present. Switch to AX_PKG_SWIG macro for versioned or unversioned swig detection.

# SYNOPSIS

# AC_PROG_SWIG([major.minor.micro])

|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro searches for a SWIG installation on your system. If found you
|
||||
# should call SWIG via $(SWIG). You can use the optional first argument to
|
||||
# check if the version of the available SWIG is greater than or equal to
|
||||
# the value of the argument. It should have the format: N[.N[.N]] (N is a
|
||||
# number between 0 and 999. Only the first N is mandatory.)
|
||||
# This macro searches for a SWIG installation on your system. If found,
|
||||
# then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is
|
||||
# found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd.
|
||||
#
|
||||
# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
|
||||
# the swig package is this version number or higher.
|
||||
# You can use the optional first argument to check if the version of the
|
||||
# available SWIG is greater than or equal to the value of the argument. It
|
||||
# should have the format: N[.N[.N]] (N is a number between 0 and 999. Only
|
||||
# the first N is mandatory.) If the version argument is given (e.g.
|
||||
# 1.3.17), AX_PKG_SWIG checks that the swig package is this version number
|
||||
# or higher.
|
||||
#
|
||||
# As usual, action-if-found is executed if SWIG is found, otherwise
|
||||
# action-if-not-found is executed.
|
||||
#
|
||||
# In configure.in, use as:
|
||||
#
|
||||
# AC_PROG_SWIG(1.3.17)
|

# SWIG_ENABLE_CXX
|
||||
# SWIG_MULTI_MODULE_SUPPORT
