Cargo Features

exe has no features set by default.

[dependencies]
exe = { version = "0.5.6", features = ["win32"] }
win32 = winapi

Affects exe::valloc, pe::PE.is_allocated

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
