Quoting the Allegro documentation:
\begin{quote}
When creating the main window, Allegro searches the executable for an ICON
resource named "allegro_icon". If it is present, Allegro automatically
loads it and uses it as its application icon. Otherwise, Allegro uses the
default IDI_APPLICATION icon.
\end{quote}
I take it this implies that Allegro first looks for a resource named
`allegro_icon' and then for one named `IDI_APPLICATION'. However, if it
doesn't find `allegro_icon', it uses a default Windows icon even if the
resources for the program specify IDI_APPLICATION. At least, that's what
happens under MinGW.
I've attached a patch that makes Allegro check the IDI_APPLICATION resource
for the running program prior to falling back on the Windows default.--- all3938\src\win\wwnd.c Sun Sep 16 18:31:56 2001
