Обсуждение: MSYS2 support
There were a number of recent threads about building PostgreSQL on MSYS2. This has been confusing on occasion; see for example [0]. MSYS2 is actually a derivative of Cygwin. What most people are actually doing is using MSYS2 has the host environment for doing a kind of cross-compilation to MinGW. You can also build natively on MSYS2, using the existing Cygwin support. Except that it won't work because configure doesn't recognize the config.guess output. Attached are a couple of small patches to fix that up. The first patch fixes configure as explained. The second patch fixes some warnings in ps_status.c. It's curious why the existing build farm members don't issue warnings there, but maybe their compilers are too old. The third patch fixes another warning; again, not sure why original Cygwin doesn't warn. It might be a bit too broad to apply like that. MSYS2 doesn't ship with cygserver AFAICT, so you can't run a PostgreSQL server, but everything else should work.

They were also useful for more recent Cygwin versions than the build farm currently has. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
