despite passing -mno-cygwin as a gnatmake option and additionally as a gnatlink
option, gnatlink adds the cygwin path to adalib to the link command. The
libgnat
is found first in the cygwin path and not in the mingw path. The link
consequently fails.
The problem is present on both gcc-3.3.3 and gcc-3.4.1
