     14The reason of this is a name clash: there are two different libraries called ecl.dll.
     15One in SAGE_LOCAL/lib/ and one in SAGE_LOCAL/lib/python/site-packages/sage/libs/
     16It is the second one whose importing fails because it should be linked to the first one, but cygcheck shows that this dependency is resolved to itself!
     17This is of course dysfunctional, whence the import failure.

     19The easiest solution would be to rename sage/libs/ecl.pyx to something else,thus avoiding a name clash.
     20The solution proposed here is different and more indirect:
     21patch ECL build system so that it follows the name convention proposed by Cygwin.
     22The shared library itself is now in SAGE_LOCAL/bin/cygecl.dll.
     23In addition, an import file is created in SAGE_LOCAL/lib/libecl.dll.a.
