This patch fixes most of current reasons to generate compiler warnings.
The changes consist of:
- adding missing casts
- hiding or unhiding function declarations
- including headers where missing
- add __UNCONST when assigning a const char * to a char *
- adding missing return statements
- changing some types from unsigned to signed, as the code seems to want
signed ints
- converting old-style function definitions to current style (i.e.,
void func(param1, param2) short param1, param2; {...} to
void func (short param1, short param2) {...})
- making the compiler silent about signed vs unsigned comparisons. We
have too many of those in the new libc to fix.
A number of bugs in the test set were fixed. These bugs were never
triggered with our old libc. Consequently, these tests are now forced to
link with the new libc or they will generate errors (in particular tests 43
and 55).
Most changes in NetBSD libc are limited to moving aroudn "#ifndef __minix"
or stuff related to Minix-specific things (code in sys-minix or gen/minix).
1. ack, a.out, minix headers (moved to /usr/include.ack),
minix libc
2. gcc/clang, elf, netbsd headers (moved to /usr/include),
netbsd libc (moved to /usr/lib)
So this obsoletes the /usr/netbsd hierarchy.
No special invocation for netbsd libc necessary - it's always used
for gcc/clang.
3 sets of libraries are built now:
. ack: all libraries that ack can compile (/usr/lib/i386/)
. clang+elf: all libraries with minix headers (/usr/lib/)
. clang+elf: all libraries with netbsd headers (/usr/netbsd/)
Once everything can be compiled with netbsd libraries and headers, the
/usr/netbsd hierarchy will be obsolete and its libraries compiled with
netbsd headers will be installed in /usr/lib, and its headers
in /usr/include. (i.e. minix libc and current minix headers set
will be gone.)
To use the NetBSD libc system (libraries + headers) before
it is the default libc, see:

This wiki page also documents the maintenance of the patch
files of minix-specific changes to imported NetBSD code.
Changes in this commit:

. Add <sys/sigcontext.h> in compat library.
. Remove dependency file in tree.
. Enable compilation of common/lib/libc/atomic in libsys
. Do not generate RCSID strings in libc.
. Temporarily disable zoneinfo as they are incompatible with NetBSD format
. obj-nbsd for .gitignore
. Procfs: use only integer arithmetic. (Antoine Leca)
. Increase ramdisk size to create NBSD-based images.
. Remove INCSYMLINKS handling hack.
. Add nbsd_include/sys/exec_elf.h
. Enable ELF compilation with NBSD libc.
. Add 'make nbsdsrc' in tools to download reference NetBSD sources.
. Automate minix-port.patch creation.
. Avoid using fstavfs() as it is *extremely* slow and unneeded.
. Set err() as PRIVATE to avoid name clash with libc.
. [NBSD] servers/vm: remove compilation warnings.
. u32 is not a long in NBSD headers.
. UPDATING info on netbsd hierarchy
. commands fixes for netbsd libc
to upstream.
- revert to upstream version of function prototypes for
setting the uid and gid fields of the archive_entry.
- move uid/gid overflow checks into header_common().
- use archive_set_error() instead of fprintf() for getting
error message text back to the main program.
The file timestamps in archives created by libarchive all had
dates in the year 2038. It was caused by a bit shift in
archive_write_set_format_ustar which shifted 1 instead of 1ull.
