Toolchains and libraries for the ucrt64 compilers in rtools40.
This reposity has several extra package rtools-packages used only for the toolchains that target the UCRT:
- Latest git version of mingw-w64-{headers,crt} (many ucrt related fixes)
- Static build of mingw-w64 winpthreads
- Latest stable version of GCC-10
- Recent version of ICU.
- Recent version of tcl/tk
We only deploy these for the new ucrt64 toolchains. All other ucrt packages are built from rtools-packages just like the mingw32 and mingw64 binaries used by Rtools 4.0 and up.
