This is not the w32api you are looking for. This package provides the header files and import libraries constituting a standard API for the development of applications which utilise the capabilities of the 32-bit MS-Windows system dynamic link libraries, configured specifically for use with the MSYS System Builder (msys-dvlpr) toolset. It should be installed into the / == /usr (that is, C:\msys\1.0) directory, and NOT intoo the usual MinGW location /mingw (C:\MinGW). Install this component only if you intend to create MSYS-dependent applications.
