+* Add to the PE/PE+ targets the support of two different kinds of
+ pseudo-relocations. They can be selected by the switches
+ --enable-runtime-pseudo-reloc-v1 and --enable-runtime-pseudo-reloc-v2.
+ For the switch --enable-runtime-pseudo-reloc it uses for 32-bit
+ runtime pseudo relocation version one, for 64-bit the version two.
+
Changes in 2.19:
* Linker scripts support a new INSERT command that makes it easier to
