Public domain POSIX make

Public domain POSIX make

This is an implementation of POSIX make.

It comes with its own makefile, naturally, and should build on most modernish Unix-style systems. (Command line options may not work properly on BSD: search for 'BSD' in main.c and adjust to suit.)

In its default configuration only POSIX features are supported. Some extensions can be enabled by setting ENABLE_FEATURE_MAKE_EXTENSIONS to 1. These are largely compatible with GNU make:

• double-colon rules
• -include to ignore missing include files
• ifdef/ifndef/else/endif conditionals
• lib.a(mem1.o mem2.o...) syntax for archive members
• :=/+=/?=/!= macro assignments
• macro expansions can be nested
• chained inference rules
• */?/[] wildcards for filenames in target rules

When extensions are enabled adding the .POSIX target to your makefile will disable them. Other versions of make tend to allow extensions even in POSIX mode.
