Thanks Jeff.
The attached patch is an attempt to implement this for
newlib/libc/machine/sys/hppa. It now compiles. Could
you review the attached patch newlib-hppa.diff please?
libgloss/pa is now the failure point.
make[2]: Leaving directory
`/opt/usr3/ftp_archive/gnu/gcc/ss/b3.1-branch/b-hppa1.1-proelf/hppa1.1-proelf/libgloss/libnosys'
make[2]: Entering directory
`/opt/usr3/ftp_archive/gnu/gcc/ss/b3.1-branch/b-hppa1.1-proelf/hppa1.1-proelf/libgloss/pa'
make[2]: *** No targets specified and no makefile found. Stop.
I have addressed all differences between the m68k and pa configure.in
files locally but it still does not seem to fix it.
Thanks.
