+# This macro, given a program counter value and the name of the
+# function in which that PC resides (which can be null if the name is
+# not known), returns nonzero if the PC and name show that we are in
+# sigtramp.

+# On most machines just see if the name is sigtramp (and if we have
+# no name, assume we are not in sigtramp).

+# This means PC_IN_SIGTRAMP function can't be implemented by doing its
