# This is for a MIPS running RISC/os 4.52C.

# if a library is compiled with the bsd headers and gets linked with the
# sysv system libraries all hell can break loose (e.g. a jmp_buf might be
# a different size).
# ptrace(2) apparently has problems in the BSD environment. No workaround is
# known except to select the sysv environment. Could we use /proc instead?
# These "sysv environments" and "bsd environments" often end up being a pain.
#
# This is not part of CFLAGS because perhaps not all C compilers have this
