Good assumption ;)

Ok, well, I´m so still wondering why didn´t I take a look at the 
Compiler log. :(
Just installed Dev-cpp 4.9.8.0 -got some problems when making a SDL 
1.2.5 devpack, although finally it works! Dev-Cpp v4.9.8.0 DOES paas the 
-pg option to the linker. Actually profiling works flawless.
But as you state, in 4.9.8.1 does not, so I also think it´s a bug.

That was the same workaround I used, but I wanted to know if I was doing 
something wrong :)

Thanks for the link and help.
