5 (see `automake --help' or the manual for a list of them).
6 * Honor the WARNINGS environment variable.
7 * Omit the call to depcomp when using gcc3: call the compiler directly.

9 when `make installcheck' is run. This is enabled by --gnits.

13 * `+=' can be used in conditionals, even if the augmented variable

35 * EXTRA_DIST can contain generated directories.
36 * Support for dot-less extensions in suffix rules.

50 It is also possible to pass a list of global Automake options as
51 first argument to this new form of AM_INIT_AUTOMAKE.
52 * Compiler-based assembler is now called `CCAS'; people expected `AS'
53 to be a real assembler.
