Thanks for your response.

It doesn't work. Moving DEFINE_EVENT_TYPE() to header x.h or moving 
DECLARE_EVENT_TYPE() + DEFINE_EVENT_TYPE() to both cpp files results in 
similar linker error:
x.o:x.cpp:(.bss+0x0): multiple definition of `EVT_GOT_EXT_APP_INPUT'
y.o:y.cpp:(.bss+0x0): first defined here

It seems that doubling DEFINE_EVENT_TYPE() for one event causes this 
error. This is what online manual says about custom events  (in "Event 
handling overview" section):
[...] this is done using the following macros:
// in the header of the source file
DECLARE_EVENT_TYPE(name, value)
// in the implementation
DEFINE_EVENT_TYPE(name)

As far as I understand this situation:
- DECLARE_EVENT_TYPE() is something like function declaration so it 
should go into headers to provide informations for linker.
- DEFINE_EVENT_TYPE() is something like function defition so it is an 
implementation

Did I miss something??

Also sample provided with wxwidgets does't resolve my problem, because 
in this sample events aren't splitted into multiple files.

Take into consideration that my code was compiling perfectly well under 
VC++ 7.0. This linker problem occurs under mingw32.

Any ideas??
