Appears to build fine (several .configs tried)

Will spare us quite some likely()/unlikely() occurances.

ldso and syscalls are __always_inline (the latter would need more cleanup)

Note that gamma_r is not provided by glibc, perhaps add a SUN specific knob later

Do noy use syscall wrapper based on INTERNAL_SYSCALL.
A proper fix would require an arch specific implementation.

__extern_inline macro, this also makes gcc 4.3 happy.

- Implements sleep(3) for !UCLIBC_HAVE_REALTIME
- Implements usleep(3) for !UCLIBC_HAVE_REALTIME
- adds #warning about incorrect posix_fadvise{,64}()
- removes unused and unwanted uselib()
Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

For -combine, make sure that we don't pollute our non-varargs mremap decl
with some vararg decl from later in the TU by putting ours after anybody
else who is picking up mman.h.
This is admittedly a small work-around..
smallish testcase:
$ cat bug.h
extern void *mremap (void*, unsigned, unsigned, int, ...);
$ cat bug1.c
#include "bug.h"
int whatever;
$ cat bug2.c
#define mremap _hidemremap
#include "bug.h"
#undef mremap
void *mremap (void*, unsigned, unsigned, int, void*);
$ gcc -c bug1.c bug2.c
$ gcc -c bug1.c bug2.c -combine
bug2.c:4: error: conflicting types for ‘mremap’
bug.h:1: error: previous declaration of ‘mremap’ was here

were removed in linux-2.6
|
|

in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

- pull bits/fcntl.h from glibc (Timo Teräs)

The only code change observed is actually a case
where we were not doing that as needed:

-53 push %ebx
-e8 00 00 00 00 call 6 <__GI_tzset+0x6>

6a 00 push $0x0
-e8 fc ff ff ff call 10 <__GI_tzset+0x10>
- R_386_PLT32 time
+e8 fc ff ff ff call 3 <__GI_tzset+0x3>
+ R_386_PC32 __GI_time
3d ff 4e 98 45 cmp $0x45984eff,%eax
0f 9e c0 setle %al
0f b6 c0 movzbl %al,%eax
50 push %eax
-e8 fc ff ff ff call 21 <__GI_tzset+0x21>

R_386_PC32 _time_tzset
58 pop %eax
5a pop %edx
-5b pop %ebx
c3 ret
No mass migration of libc_hidden_proto(foo) planned.
Lets wait for potential fallout first.
