2.4.4-pre6 does not compile

[Jochen Striepe]

        Hi,

2.4.4-pre6 actually is the 4th 2.4.4pre-Patch that does not compile
without further patching on my system. :-(

Its because you're using a version of gcc which doesn't have
__builtin_expect (eg, egcs 1.1.2, some versions of gcc 2.95).
I'm told that gcc 2.95.[12] are not suitable for kernel compilation...

I've currently got the following in my tree (sorry, no diff since I've
got other changes in this file).  lib/rwsem.c, line 9, add:

#if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 96)
#define __builtin_expect(exp,c) (exp)
#endif

I'm not sure if this is correct, or which compilers work, which don't
(so don't anyone go and drop it into Linus/Alans kernels), but it
seems to work for me.

No 2.95.x has __builtin_expect.  There might be some 2.95-derived GNUpro that 
supports it but I doubt anyone is using those to build kernels.

same problem here.
i'm using
# gcc -v
Reading specs from /usr/lib/gcc-lib/i486-suse-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)

and this one has successfully built the last couple of kernels. if
compiler requirements have changed, may i humbly suggest to add this
to the pre-patch logfile ?

btw: i have installed clean vanilla sources. the only  possible
source of pollution was my old .config, which i copied into the tree
before making menuconfig. but this has always worked before.

regards,

jörn

(please cc: me, i only read the archives, which have some lag.
thanks.)
