Hi,

There are no crtbeginS.o nor crtendS.o on linux/alpha/elf.

Thanks.

Other Linuxes are fine. Somehow they have defined HANDLE_SYSV_PRAGMA.

For linux/x86 and linux/m68k, they include the generic linux.h which
includes the generic svr4.h where HANDLE_SYSV_PRAGMA is defined. For
others, we have to make sure HANDLE_SYSV_PRAGMA is defined somehow.
From what I can see, they, except linux/alpha, are ok.

OK.  Can you send me a patch to fix this problem for the other linux
configs?  I'll go ahead and install the patch into the alpha linux.h.

Yes, it is the case.

Yes, there is a generic linux.h. But the files in the config subdir
are so messed up that linux/alpha and linux/sparc cannot use the
generic linux.h. BTW, you haven't seen the linux/mips patch yet.

If that's the case, then shouldn't all the other linux configurations
have HANDLE_SYSV_PRAGMA defined?  I only see it arm/linux.  Or better
yet, don't we have a generic linux.h  where we could put this kind
of thing?

[H.J. Lu]

The Linux compiler should take

#pragma xxxxxxxxxx

I added it to linux/alpha.
