Any of the libraries for g++, g77, or objc may fail to build if you don't 
clean out their build directories, as well as doing a make clean, when 
starting over.  The configure option --enable-languages='c++,f77,objc,gcov' 
in place of David's --disable-libgcj will get you all the pieces which work 
out of the box on cygwin.  There are a few lines to fix in cygwin's 
target.exp if you want to run the test suite, which you can do with cygwin's 
dejagnu, except for the g++ libraries.  The special dejagnu for the g++ 
libraries is not easily found.
