My problem is in src/sys/ufs/ffs/ffs_bswap.c which contains : #include =20=

This should reference, I guess,  src/sys/ufs/ffs/fs.h. But, at least on =20=

my system, /usr/include/ufs/ffs/fs.h exists and does not contain some =20=

struct fields needed by NetBSD. I guess that's what gets really =20
included (and that shouldn't). That's why I thought of -nostdinc.

(all that trouble for cross building for mac68k a tool, installboot =20
which is not relevant for mac68k....)

I'm using MacOs X 10.2.4.
rzara@lundi [~] {1}% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.1/specs
Thread model: posix
Apple Computer, Inc. GCC version 1175, based on gcc version 3.1 =20
20020420 (prerelease)

  I've put the NetBSD sources on an UFS disk image, because HFS+ is =20
(somewhat) case insensitive and this cause a problem for (at least) the =20=

cvs sources.
