Re: [autoconf] Program & Library, dev in parallel?

[mpsuzuki]

A possible approarch might be "install-only-different-files".
"install" of GNU coreutils has an option "-p" to preserve the
timestamp of source file. If it works well, although all headers 
& libraries are reinstalled, the timestamps of unchanged files
are not updated, so rebuilding of the application would be
minimized.

Another approarch might be using "built-but-not-installed-yet"
library. I think pkg-config's "uninstalled" feature is similar,
but autoconf does not provide convenient macros to do such...
