This causes the proc-macro feature to be ignored for wasm-targets where proc-macro is not available. Currently, if a crate is to be built on wasm that depends on
syn, the proc-macro feature from an actual proc-macro leaks into the build-environment ofsyn, causing the build to fail.This patch enables me to build (and run) my crate on wasm-targets.
I'd be nice if this could be bumped into a 0.14 release. This is a concerted effort with proc-macro2,
syn,quoteand stdweb; all of which need patching to compile on wasm.
