Hi,
You should provide a compilable example that demonstrates the problem, so the problem can be fixed. I have no idea about a specific revision that might have introduced this problem.
building LCL with OPT="-Cr" causes the problem in anchoreditor.pas (Assembling (pipe) /Users/{standard input}:3839:suffix or operands invalid for `cmovns') . Used lazarus svn 30302 and fpc svn 17324. OSX 10.5.7.
I mentioned the problem in bugs.freepascal.org issue 19117 which is unrelated (range check errors in LCL). Let me know if you want me to create a new issue.
