Pub serve in DDC mode doesn't work for project from web/subdir

Environment: Windows 10, Dart SDK 1.24.0-dev.5.0.
Steps:

• Unzip the attached project, run pub get.
• Run pub serve from the command line.
• Open http://localhost:8080/subdir/index.html in Chrome. The app works just fine.
• Restart pub in DDC mode: pub serve --compiler=dartdevc.
• Open http://localhost:8080/subdir/index.html in Chrome. The app doesn't load.

This has been fixed already actually, the 1.24.0-dev.6.0 release should work (I also tested this project with my locally built sdk and it works).

FWIW the problem is still reproduced with

dartsdk-windows-x64-release.zip	24-May-2017 13:42	58.7M	"a5033a1906eb6a6b9113995ec6c449ff"

from http://gsdview.appspot.com/dart-archive/channels/dev/raw/1.24.0-dev.6.0/sdk/

It is probably a windows specific issue, investigating further

[jakemac53]

Alright, confirmed this is reproducible on windows. It looks like the library name for the module is missing the subdirectory portion on windows, so we try to call main() on a non-existing library.

[jakemac53]

Fwiw, resolving dart-lang/sdk#27262 would likely solve this issue.
