Bug #7710: [mingw] r38839 breaks build
https://bugs.ruby-lang.org/issues/7710

Author: jonforums (Jon Forums)
Status: Open
Priority: Normal
Assignee: nobu (Nobuyoshi Nakada)
Category: build
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2013-01-14 trunk 38808) [i386-mingw32]


On my Win7 32bit system using mingw-w64 gcc 4.7.2 and the RubyInstaller build recipes I get the following failure

make[2]: Entering directory `/c/projects/rubyinstaller-git/sandbox/ruby19_build/ext/ripper'
extracting ripper.y from ../../../../../../Users/Jon/Documents/RubyDev/ruby-git/parse.y
id.h not found in ["..\\..\\..\\..\\..\\..\\Users\\Jon\\Documents\\RubyDev\\ruby-git\\ext\\ripper;..\\..;..\\..\\.ext\\include\\i386-mingw32\\ruby;..\\..\\..\\..\\..\\..\\Users\\Jon\\Documents\\RubyDev\\ruby-git\\include\\ruby;..\\..;..\\..\\..\\..\\..\\..\\Users\\Jon\\Documents\\RubyDev\\ruby-git"]
make[2]: *** [ripper.y] Error 1
make[2]: Leaving directory `/c/projects/rubyinstaller-git/sandbox/ruby19_build/ext/ripper'
make[1]: *** [ext/ripper/all] Error 2
make[1]: Leaving directory `/c/projects/rubyinstaller-git/sandbox/ruby19_build'
make: *** [build-ext] Error 2

due to `id.h` not being found.

The same failure is occurring on the RubyInstaller CI: http://ci.rubyinstaller.org/job/ruby-trunk-x86-build/820/console

While placing `id.h` in `ext/ripper` enabled a successful rebuild, havoc reigned during `make test-all`. Reverting r38839 fixed the issue.

FWIW, in both the passing and failing cases my `rbconfig.rb` contains

  CONFIG["PATH_SEPARATOR"] = ":"

I won't have time to play with `configure.in` to see if changing the separator to ";" on mingw will also fix the issue, but I'm sceptical given the test-all failures.

As previous *nix and win7 builds were fine, why was this change needed?
