To follow up my own post:

egcs-980824 fails to compile rtems' c/src/lib/libnetworking/netinet/if_input.c for the SH1 (!!) if
trying to compile it with -O2 or greater:

/opt/gnu/bin/sh-rtems-gcc --pipe  -m1 -Wall -ansi -fasm -g
-B/lfs/poseidon/users/rtems/build/sh-rtems/gensh1/lib/ -specs bsp_specs -qrtems
-I/lfs/poseidon/users/rtems/build/sh-rtems/gensh1/lib/include/networking -D_COMPILING_BSD_KERNEL_
-DKERNEL -DINET -DNFS -DDIAGNOSTIC -DBOOTP_COMPAT  -O2 -Wno-unused -qrtems_debug    -c -o
o-gensh1-debug/ip_input.o /users/rtems/src/rtems-980824/c/src/lib/libnetworking/netinet/ip_input.c
cpp: output pipe has been closed
