I missed a bit. This is Lazarus trunk on FPC 2.7.1, and at the start of 
the project build (i.e. the point at which I tell it to build an app) 
the console shows

[TMainIDE.DoRunProject] A
TMainIDE.DoInitProjectRun A True 0
TMainIDE.DoInitProjectRun B
TLazPackageGraph.CheckIfCurPkgOutDirNeedsCompile  Compiler custom params 
changed for FCL 1.0.1
   Old=" -MObjFPC -Scghi -O1 -gl -vewnhi -l fcllaz.pas"
   Now=" -MObjFPC -Scghi -O1 -gw2 -godwarfsets -gl -vewnhi -l -gw -gl 
-godwarfsets -gh -gt -Co -Cr -Ci -Sa fcllaz.pas"
