# Makefile for less using mingw-w64 package:
# http://mingw-w64.org/doku.php
#
# Derived from Makefile.wnm
#
# Usage: mingw32-make -f Makefile.wng [REGEX_PACKAGE={posix|gnu|regcomp-local}]
#
# The optional command line parameter "REGEX_PACKAGE" is used to specify
# a regular expression package for compilation and linking. This parameter
# can assume one of three values.
#
# REGEX_PACKAGE == regcomp-local
# This choice selects the regular expression package written by Henry
# Spencer. It is implemented by the repository file "regexp.c".
#
# REGEX_PACKAGE == posix
# This choice selects the POSIX implementation and is provided by MingW.
# This is the default choice.
#
# REGEX_PACKAGE == gnu
# This choice selects the GNU implementation and is provided by MingW.
#
#### Start of system configuration section. ####

# and library that provide regular expression support.
