2.4.7 Windows Install Using a ZIP Package

1. Download the binary zip package from http://sdcc.sf.net/snap.php and unpack it using your favorite unpacking tool (gunzip, WinZip, etc). This should unpack to a group of sub-directories. An example directory structure after unpacking the mingw32 package is: c:\sdcc\bin for the executables, c:\sdcc\include and c:\sdcc\lib for the include and libraries.
2. Adjust your environment variable PATH to include the location of the bin directory or start sdcc using the full path.
