Suppose a makefile or similar for this issue, would handle only man
pages that have changed since the last update:


The TL;DR version of the issue is that compilation of database is slow and
prone to fail, plus the database should be re-indexed each time a page is
added, removed or changed.
If Cygwin do this only at man-db postinstall, the database WILL go out of
reality pretty soon.
