Failure building gui under Windows

[Tom Koelman]

Hi,

again I am trying to get gui building under Windows 2000.

I followed the instructions in README.MinGW and needed the following
patch to that document to get trough the configure stage:

   Unpack and install. You can put them in the standard locations, or also:
   the header (.h) files in $GNUSTEP_SYSTEM_ROOT/Library/Headers
   the library (.lib) files in $GNUSTEP_SYSTEM_ROOT/Library/Libraries
   the dll files in $GNUSTEP_SYSTEM_ROOT/Tools
 
+  Be sure to rename the .lib files to .a!

 Building and installing GNUstep-gui
 -----------------------------------
 

However, typing

make install

in the directory containing the gui 0.9.4 source now fails with the
following error:

How do I solve these conflicting INT32 types to get gui going?
