[Lazarus] Custom defines don't work?

[Reinier Olislagers]

Hi list,

Laz trunk, fpc trunk x86, Win.

I'm trying to set up some defines based on the FPC version [1]:

In project options,compiler options,other,conditionals I add this:

// Optimize hash functions for FPC trunk
// FPC 2.6.x does not support -OoUSEEBP
if FPC_FULLVERSION>=20701 then
begin
  UsageCustomOptions += '-OoUSEEBP -dOPTIMIZESHA1 -dOPTIMIZEMD5'
end;

However, -OoUSEEBP etc don't show up in the options when I click Show
Options

1. Am I doing something wrong or is this a bug?
2. Is there an easier way of doing this?

Thanks.
