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

+# This is needed for GDB, but needs to be in the top-level make because
+# 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
+# option.
