These blocks mostly consisted of redundant structure, following the same
#ifndef pattern over and over, with only minimal variation.
It's easier to maintain if the common structure is only written once and
encapsulated in a macro.
To avoid "defined but unused" warnings from GCC in the case where
MAKE_NATIVE is not defined, I had to add volatile. Adding
MAKE_ATTR_UNUSED alone would not preserve the rcsid variable in the
resulting binary.
NetBSD make is intended to be maximally portable, therefore it uses only
C89. This was not declared in the Makefile before.
There are still a few places in parse.c and metachar.c that use
end-of-line comments. These will be fixed in a follow-up commit.
Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.
Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.
way to get gettimeofday(), etc. On some systems on which you might want
to host make (e.g. solaris), <time.h> won't get you a struct timeval
definition.
