Windows builds of the GTK frontend use the pie flag to compile
hexchat.exe. Windows needs an explicit entrypoint when compiling with
--pie, otherwise an invalid executable is created.
This sets the entrypoint of the executable on Windows (as it is
currently set in the Visual Studio project files).
This fixes a critical build issue which prevents all Windows builds
using Meson from working.
Quick rundown of benefits:
- Much faster:
- Autotools (with autogen): 22 seconds
- Meson: 7 seconds
- Meson (with ccache): 2 seconds
- Simpler:
- ~1000 lines smaller
- Single simple language
- Potentially better Windows (Visual Studio) support
What is not done:
- Complete Windows support
- OSX support (easy)
