+
+2001-11-29 Jonathan Larmour <jlarmour@redhat.com>
+
+ * include/errno.h: Don't use 'const' type qualifier any more. It

+// Purpose: To provide a common set of error codes
+// Description: This provides a common set of error codes that all
+// packages can agree on. It doesn't preclude them defining
+// their own error return system, but this is a preferable
+// system to use to help error support be as general as
+// possible.
+//
+// We try and conform to the ANSI/POSIX error code format,
+// namely starting with the character 'E'
+//
+// Usage: #include <cyg/error/codes.h>
+//
+// Example:
+//
+// err=myfun();
+// if (err != ENOERR)
+// {
+// str=strerror(err);
+// printf("myfun returned error: %s\n", str);
+// }
+// else ....
