-\* Sibs is intended to work on as many platforms as possible, you can help by porting sibs to another platform. Should only be minor changes if the platform is unix-like.
+(1). Msvc, mingw-w64 and cygwin are supported. Cygwin is defined as a linux platform while mingw-w64 is defined as a windows system.
