+/* This is an implementation of the __eprintf function which is
+   compatible with the assert.h which is distributed with gcc.
+
+   This function is provided because in some cases libgcc.a will not
+   provide __eprintf.  This will happen if inhibit_libc is defined,
+   which is done because at the time that libgcc2.c is compiled, the
+   correct <stdio.h> may not be available.  newlib provides its own
+   copy of assert.h, which calls __assert, not __eprintf.  However, in
+   some cases you may accidentally wind up compiling with the gcc
+   assert.h.  In such a case, this __eprintf will be used if there
+   does not happen to be one in libgcc2.c.  */
