Where is the source corresponding to GPC 20070904? Where should I find the .gpi files for supplied units (like unit GPC)? If I install a binary distribution for Windows, is there a follow-up step that must be performed manually? (like compiling GPC.PAS) Where would I find documentation of the entry points provided by unit GPC? I downloaded and installed dev_gnu_pascal-1.9.4.13.exe I started with mingw-get-inst-20120426.exe -- It downloaded and installed whatever it wanted. From the size of dev_gnu_pascal-1.9.4.13.exe I had assumed it included the source of GPC, but I haven't been able to find it. In http://www.gnu-pascal.de/alpha, there is no gcc-core-3.4.5, and there is no gpc-20070904.
