[RFA 3/5] New patches to support --enable-targets=all for mingw64

[RFA 3/5] New patches to support --enable-targets=all for mingw64

[Pierre Muller]

  I tried to compile GDB with
--enable-targets=all for x86_64-w64-mingw32
target.
  As 'long' type is 4-byte while pointer type is 8-byte,
this target is quite sensitive to so 'dirty' code
lying around like casting 'long' or 'unsigned long' to pointers...

  I had to fix several sources to be able to 
successfully compile GDB with those configuration options.


3) Change some types from 'long' to 'CORE_ADDRESS',
if they could carry pointers.
 in coffread.c

	* coffread.c (struct coff_symbol): Change c_value type from `long' to
	`CORE_ADDRESS' as it might contain target addresses.
