4ce32d5dee Backed out previous commit (alignment suitable for RELENG_4) as planned
since it has been MFC'ed.  See the log message for the previous commit
for more details.  The alignment bug in gcc-3 has not been fixed, but
it is not very serious and the previous commit just moved it (as intended).

fb0be37ded Align the stack suitably for the version of gcc in FreeBSD-4 (provided
-fomit-frame-pointer is not used).  This is mostly moot for -current
because gcc-3 does the alignment (slightly incorrectly) in main().

This patch is intended for easy MFC'ing and should be backed out in
-current soon since it causes compiler warnings and better fixes are
possible in -current.  The best fix is to do nothing here and wait for
gcc to do stack alignment right.  gcc-3 aligns the stack in main(), but
does it too late for main()'s local variables and too late for anything
called before main().  A misaligned stack is now more than an efficiency
problem, since some SSE instructions in some or all (hardware)
implementations trap on misaligned operands even if alignment checking
is not enabled.

828191256b The main reason for this is to reduce diffs between all the crt1.c's.
Assembler macros are tidied up and made as similar as sanely possible.
The macros are translated into C (__inline static) functions for lint.

Declaration orders are made the same.
Declarations are all ISOfied and tidied up.

Comment contents have gratuitous diffs removed.

The net result is a bunch of crt1.c's that are 90% the same.
It may be possible to now encapsulate the differences in one
MD header, and have only one MI crt1.c file (although the macros
to do this may be ugly).

ccece3d626 Whitespace diffs only; this brings this file into the same whitespace
convention as src/lib/csu/*/crt1.c.

This will make the follow up diffs easier to see and extract.

2a53f3fb35 Major cleanup of bsd.lib.mk.
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything.  Added a NOINSTALLLIB knob for libpam/modules.  To not
build any library at all, just do not set LIB.

ccc4300e95 Removed "-fkeep-inline-functions" from CFLAGS, since it now has no effect
except to generate spurious warnings about a system header <sys/param.h>
having some inline functions (the bswap family).  This backs out the main
part of rev.1.5 (which was the only part left).  The problem fixed by
rev.1.5 of the Makefile went away in rev.1.5 of ../common/crtbegin.c
when the references to do_ctors() and do_dtors() in the latter were moved
from inline asm to C code.

This leaves the problem that implementation details cause warnings.

4cd0119367 Do not use __progname directly (except in [gs]etprogname(3)).
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

ee425bffeb Sparc64 ELF version of the C runtime support.
It tries to comply with the SCD 2.4.1 (and thus Sparc 64-bit psABI).

This is an amalgamation of the FreeBSD Alpha crt1.c and the BSD/OS Sparc
crt0.c (which the copyright reflects).
