I remain convinced, that the "bending into shape" ought to begin with making the additional GNU compiler front-ends (be they Ada, or Lisp, Java, Fortran, Pascal, Objective C, etc.) addable to an already existing C-compiler. I find it crazy, that every such front end currently downloads and builds its own gcc-core-SOMEVERSION, instead of using the base gcc or DEPEND-ing on lang/gccSOMEVERSION.
Yes, I am well aware, that this is, how GNU people do things. No, I don't think, there is nothing FreeBSD can do about it... Starting with making all such compilers use common binutils. (Perhaps, these can even be provided by the base -- NetBSD does just that, for example...)
Once done, ports of front-ends will no longer have to each deal with the back-end making the maintainership easier and thus giving us better ports...
Common binutils would help alot. In general, it would also be excellent to return to a schema where languages are considered plugins to GCC. The savings in disk space, build trouble, and compiler porting could be substantial.
