Re: compiling on 32-bit mingw

[Bastian M. <bma...@we...>]

Sigh. MinGW32 is falling behind rather seriously. IPrintDialogCallback 
and friends have been part of the API since Windows 2000 Pro according 
to MSDN. Mingw32 is currently also lacking support for several other 
"modern" APIs like Direct2D, DirectWrite and touch, which gnuplot might 
use in the near future. This is also not the only development 
environment with that problem: OpenWatcom's library is seriously out of 
date, too.

To fix compilation with MinGW32 for now, we could add the old code back 
along with a number of #ifdef's, or extract the missing definitions from 
MSDN and add them to the our code (easily around 100 lines), or #ifdef 
out the affected code and functionality.

Btw. Mingw64 and MSVC2015 compile gnuplot just fine.
