Gotcha, Chris straightened me out in private email.

Here's the situation I'm working with: stock RH6.1 + gcc-2.95.2 + kernel
2.2.13.  If I try any of the following:

% ../arla-0.29pre1/configure

or

% env CFLAGS="-O2 -I/usr/src/linux/include" ../arla-0.29pre1/configure

or

% ../arla-0.29pre1/configure --with-sys=/usr/src/linux/include 

I end up with pretty much the same result when compiling the code in xfs:

gcc -c  -DHAVE_CONFIG_H -DMODULE -D__KERNEL__  -DDEBUG -I.
-I../../../arla-0.29p
re1/xfs/linux -Wall -I. -I../../../arla-0.29pre1/xfs/linux/../include
-I../../in
clude -I../../../arla-0.29pre1/xfs/linux/../../include
-I/usr/athena/include -Wa
ll -Wstrict-prototypes -O2 -fomit-frame-pointer
../../../arla-0.29pre1/xfs/linux
/xfs_load.c
In file included from /usr/include/linux/fs.h:262,
                 from ../../../arla-0.29pre1/xfs/linux/xfs/xfs_locl.h:59,
                 from ../../../arla-0.29pre1/xfs/linux/xfs_load.c:39:
/usr/include/linux/hpfs_fs_i.h:5: parse error before `ino_t'

... and things stop there.  If I reinstall egcs-1.x, then things work
again.  I've done a bit of include file spelunking and I'm pretty sure I
can see where the conflict is coming from, but I can work around it if I
have a way to tell xfs, "trust me - _this_ is where you should get system
headers from", but as far as I can tell, you can't.  With the patch I sent
along, at least method #2 works.

I think the change needed in xfs/linux/Makefile.in is pretty mild. It
doesn't clobber any flags that are already being passed to gcc, so I don't
see how it'd hurt other architectures.  If I'm missing something here, or
if someone has a better sol'n, I'd be happy to hear it.

Cheers!
