Cygwin compile error

[kishima]

I faced following compile error with latest mruby on cygwin environment. I don't see this error with mruby 2.0.0.

$ rake
CC    src/array.c -> build/host/src/array.o
gcc: エラー: C:cygwin64homekishimawork_mrubykishima_mrubysrcarray.c: No such file or directory
gcc: 致命的エラー: 入力ファイルがありません
コンパイルを停止しました。

rake aborted!

I think double quotes is missing for cygwin because of the commit b7bc03a .
If I add double quotes for filenames, then this error disappeared.

We have merged #4905. Did the problem disappear?

I confirmed this issue was solved in cygwin environment. Thank you!
