+         We need to re-define the resource compiler, used by bakefile when compiling
+         resources, to the resource compiler returned by 'wx-config --rescomp' since
+         'wx-config --rescomp' returns both the name of the resource compiler to use
+         and the flags required for that compiler (rcflags are rccompiler-specific
+         and thus it would be wrong to use them with other resource compilers).
+
+         This line typically does something *only* when the Makefile.in generated
+         using this bakefile, is used on Windows with MSYS (when using Cygwin, resources
+         are not compiled at all).
+
+         NOTE: overwriting the RESCOMP variable we modify the entire Bakefile behaviour
+               for resource compilation; this could be a problem if the bakefile which
+               includes this file needs the standard Bakefile resource compiler to
+               build a non wx-based application.
