Subject: Generate an intermediate lib/compiler.com.
X-Git-Tag: release-9.2.0~179^2~3
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=7b443b4c7fb50ef7c4d31f8ebaf6c1c4bd1ded74;p=mit-scheme.git

Generate an intermediate lib/compiler.com.

We stopped installing this ages ago and hence stopped building it,
but now that each subdirectory is built in a separate process, it's
useful to avoid reloading the compiler repeatedly during the build.
