-Yes. All development happens in lock-step on all 3 target platforms. Using MinGW, not Cygwin. Note that the windows implementation currently has some limitations: in particular 64-bit build is [not fully supported yet][win64], and all executables created by rustc [depends on libgcc DLL at runtime][libgcc].

 ## Why aren't modules type-parametric?
