The Blitz page lists minimum requirements

gcc 2.95 or later, meaning 1999 or later - current version is 4.2.2
Intel C++ 7.1 or later - current version is 10.1
VC++ 7.1 or later - current version is 8.0 (9.0 within two weeks)
PGI C++ 5.1 or later - current version is 7.1
IBM C++ 7.0.0.3 or later - current version is 9.0
Sun Studio 10 or later - current version is 12

Exactly what is the problem, language-wise?
