So using --enable-single-host, which generates a single C routine from a Scheme source file, quietly disables many optimizations even when --enable-c-opt is enabled and -Wdisabled-optimization is specified.
Probably the reason why it builds so much faster than clang with `--enable-single-host`.
I don't know of any optimizations that are skipped with the default Gambit configuration (without --enable-c-opt).
So, no, this is not why gcc is faster than clang.
