This is due to some code trying to guess the location of the ECL 
executable itself. Such code is used mainly to locate the system 
libraries (libecl.{a,so}, cmp.fas, ...) and it is most useful in the 
case of Windows, where the program might be virtually anywhere. Now I 
realize that it does not make much sense in the case of embedded 
applications, in which you probably will not make any use of the 
compiler, help documentation, etc.

The following patch should solve this problem:
