Subject: Reload includes from CSourceFiles when they are modified
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=93c0466ccf46aa3d43541a1aa6a75192d237b3eb;p=builder.git

Reload includes from CSourceFiles when they are modified

Without this, -W did not cause includes to be read if they were present
in the cache.  It'll also come in handy for generated source files some
time in the future.
