Another possible Problem with the definition
TFPColor (fpc) record with word <> TColor (lazarus)
-$7FFFFFFF-1..$7FFFFFFF <> TFPReportColor (fpreport) UInt32
So you cannot use in Lazarus the 'well known' TColors. With TColor it is
also Delphi compatible.
If the defines are Lazarus compatible. It works for both systems. I can
make a patch if needed. But the teams have to IMHO to decide the best
