Haven't looked at cygport, but bash builds nearly out-of-the box from the  
original sources:

git://git.savannah.gnu.org/bash.git

Only change is

#undef HAVE_POSIX_SIGSETJMP
/*#define HAVE_POSIX_SIGSETJMP 1*/

in config.h. That is because sigsetjmp is a macro in  
/usr/include/machine/setjmp.h using setjmp and setjmp is a marco in bash  
somewhere using sigsetjmp if I recall right. This should be fixed in the  
cygwin-header.
