20 /* This file is unusual.
22 Because both libiberty and readline define xmalloc and friends, the
23 functions in this file can't appear in a library -- that will cause
26 And, because we want to turn the common code into a library, this
27 file can't live there.
29 So, it lives in gdb and is built separately by gdb and gdbserver.
30 Please be aware of this when modifying it.
32 This also explains why this file includes common-defs.h and not
33 defs.h or server.h -- we'd prefer to avoid depending on the
34 GDBSERVER define when possible, and for this file it seemed
37 #include "common/common-defs.h"
38 #include "libiberty.h"
39 #include "common/errors.h"
