Hi,

While trying to build the cross compiler for the pdp11 for linux on
an intel, i get the following compile error:

baldrick: /vol/bigfoot/gcc-pdp11/gcc-2.7.2.1# make LANGUAGES=c
cc -c -DCROSS_COMPILE -DIN_GCC   -g     -I. -I. -I./config
./config/pdp11/pdp11.c
./config/pdp11/pdp11.c: In function `output_function_epilogue':
./config/pdp11/pdp11.c:209: `frame_pointer_needed' undeclared (first use this function)
./config/pdp11/pdp11.c:209: (Each undeclared identifier is reported only once
./config/pdp11/pdp11.c:209: for each function it appears in.)
make: *** [pdp11.o] Error 1

I spoke with Michael Gschwind, who's name was mentioned in the pdp11
code. Here is what he told me.
