Don't know at what stage it was turned off, or whether it has ever
been on by default. Anyway, support for precompiled headers in a MSVC
build has presumably bit-rotted fairly badly by now. I recall when
precompiled headers was discussed maybe a year ago, and people were
saying that it should be used because it speeds up the build a lot. I
tried then, and eventually in some modules it was so broken that I
just gave up, had other things to do...

How would precompiled headers interact with how we generate
dependencies (the -showIncludes switch, with output piped to a Perl
script), for instance?

Hmm, comparing apples with oranges?
