Multiple includes of iup_datepick.c

[Heribert17]

Hello, i'm trying to compile the menu example from the example directory but i get this error message:

go run -a .
C:\Program Files\Go\pkg\tool\windows_amd64\link.exe: running gcc failed: exit status 1

Im working on Windows 10 with go version: 'go1.21.3 windows/amd64' and gcc version: 'gcc.exe (MinGW-W64 x86_64-ucrt-mcf-seh, built by Brecht Sanders) 13.2.0'

It seems as if both files .\win\iupwin_datepick.c and .\iup_datepick.c are included in the compilation.

Can you please try some earlier version, before https://github.com/gen2brain/iup-go/commit/a3b3bba3edbcfff91127b77ae3c4b592e92577df, to confirm if the update broke this? I should probably add examples to build actions.

v0.0.0-20230906093706-8b037fe6a7bd works. I get the example compiled.

I've run into the same issue, except on Windows 11 with go 1.22.1.

I can confirm that this is an issue existing on the latest commit via cross-compile from Linux to Windows as well.

With v0.0.0-20230906093706-8b037fe6a7bd it compiles just fine.
