Subject: Parallelize compiling compiler subdirectories.
X-Git-Tag: release-9.2.0~100^2~11
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=08f8651336d8e14060323911b1f80b8d2ad9b17f;p=mit-scheme.git

Parallelize compiling compiler subdirectories.

All the compiler.cbfs are the same except for the machine directory,
which is available as a symlink.
