servant-client error: Failed to build unix-2.7.2.2, only old base-compat patched

[clojurians-org]

servant library build failed with unix library error.
the related dependency chain: servant :> base-compat :> unix

eta-hackage just exist old version [base-compat] patched.
we can add base-compat >= 0.9.1 && <= 0.10.4 to resolve it.

it's better to patch the newer versions of base-compat to avoid this situation

the complete build log is attached:
