Thanks for the comments on the automake testing in the depcomp
code.
The BSD folks are a different religion from the GNU folks, so
conflicts in software interfaces are to be expected. Here
is the synopsis of the c89 compiler in FreeBSD 5.0:
NAME
c89 - POSIX.2 C language compiler
SYNOPSIS
c89 [-c] [-D name[=value]] ... [-E] [-g] [-I directory ...]
[-L directory ...] [-o outfile] [-O] [-s] [-U name ...]
operand ...
DESCRIPTION
This is the name of the C language compiler as required by the
IEEE Std
1003.2 (``POSIX.2'') standard.
In FreeBSD 6.1, we have
NAME
c89 -- POSIX.2 C language compiler
SYNOPSIS
c89 [-cEgOs] [-D name[=value]] ... [-I directory] ... [-L
directory] ...
[-o outfile] [-U name] ... operand ...
In NetBSD 1.6 and 3.0, we have
SYNOPSIS
c89 [-pedantic] [-pedantic-errors] [-D_ANSI_SOURCE] [options ...]
DESCRIPTION
Calls the C compiler (cc) with the given options, using a C
language
environment compatible with the ANSI X3.159-1989 (``ANSI C89'')
specifi-
cation.
STANDARDS
c89 conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
HISTORY
c89 appeared in NetBSD 1.4.
OpenBSD 3.5 and 3.9 are Western Orthodox, and thus don't provide
either c89 or c99.
Here is what POSIX (IEEE Std 1003.1-2001: Revision of IEEE Std
1003.1-1996 and IEEE Std 1003.2-1992) has to say:
8176 NAME
8177 c99 -- compile standard C programs
8178 SYNOPSIS
8179 CD c99 [-c] [-D name[=value]]...[-E] [-g] [-I directory] ...
[-L directory]
8180 ... [-o outfile] [-Ooptlevel] [-s] [-U name]...
operand ...
8181
8182 DESCRIPTION
8183 The c99 utility is an interface to the standard C
compilation system; it shall accept source code
8184 conforming to the ISO C standard. The system conceptually
consists of a compiler and link
8185 editor. The files referenced by operands shall be compiled
and linked to produce an executable
8186 file. (It is unspecified whether the linking occurs
entirely within the operation of c99; some
8187 implementations may produce objects that are not fully
resolved until the file is executed.)
...
8518 The c99 utility is based on the c89 utility originally
introduced in the ISO POSIX-2: 1993 standard.
...
9065 The c99 utility is added as a replacement for c89, which is
withdrawn in this issue.
As far as I can see, POSIX-2001's requirements for compiler options
are met by the BSD c89 and c99. In particular, there are no
provisions for generation of dependencies, like gcc's -M option family
offers.
I've never understood why some packages feel the need to generate
dependencies at build time at every end-user site, rather than at a
single developer site. In my own packages, I maintain the Makefile
dependencies myself, and don't require their generation during builds.
