glibc on sh4, redeclaration of ntohl

[Dimi Shahbaz]

Hi,
I'm trying to build glibc for sh4.  After installing the kernel headers 
to the right place and building binutils and gcc for the target, I try 
to build glibc.  All seems to be building fine, until:

In file included from ../include/netinet/in.h:1,
                  from ../resolv/resolv.h:64,

                  from thread_dbP.h:8,
                  from td_init.c:21:

                  from ../linuxthreads/internals.h:23,
                  from thread_dbP.h:8,
                  from td_init.c:21:

My hack was to comment out the offending lines from 
glibc-2.2.5/inet/netinet/in.h.  This gets the build to finish, but it's 
pretty crude.

Another approach might be to #undef the 4 functions just before the 
redefining lines in netinet/in.h.  This would allow the kernel to have 
it's own versions of the functions, and userspace programs who include 
netinet/in.h to have their own as well.

Has anyone else ran into this problem?

Thanks
Dimi
