I'll push a repair. This bug turns out not to be be extflonum-specific: it affects flonums, too. Thanks for finding it! > 2. Windows build.

I had a similar thought, but what about the various functions that the C library provides, such as powl() and cosl()? It may be possible to compile and link a MinGW-based DLL to provide those functions, and then dynamically load them for use by an MSVC-compiled executable. (The DLL could be added to the set of separately build DLLs that are downloaded during a Racket build.) _________________________ Racket Developers list: http://lists.racket-lang.org/dev
