[Lazarus] Error while compiling resources

[Dave Coventry]

I tried to take my project across to Windows and compile it there as
my Linux Lazarus intall is borked, but I kept getting the above error
whenever I tried to compile.

Google suggest that this is because of {$IFDEF WINDOWS}{$R
lclimager.rc}{$ENDIF} however none of the incarnations of my Project
uses that directive.

When I created a new project it compiled fine... until I saved it,
after which the error occurred, even in a simple app with a blank
form.

I'm running Lazarus 0.9.30.4 r35940 FPC 2.6.0 i386-win32-win32/win64
on XP in a Virtualbox VM.
