We are among the major contributors to GnuCOBOL, we use https://github.com/OCamlPro/gnucobol to review our contributions before pushing them on the SVN of Sourceforge.
Cobolworx is indeed working on a gcc frontend for COBOL. It's an impressive work (that was presented at FOSDEM this year), but less mature than GnuCOBOL, and tied to gcc, whereas GnuCOBOL can work with any C compiler (llvm, msvc, etc.) by translating COBOL to C.
Though we desig SuperBOL to work with GnuCOBOL, it could also be used with GCOBOL when it will be officially stable.
