The thing is that RHIDE adds -g by default (I think, at least my 
installation does it), because in an IDE it appears to be highly
probable the user not only wants to build the program, but also
debug. Hence, what comes out of RHIDE is usually with debugging
symbols. But you can always say
  strip foo.exe
after your done.

One more comment about filesizes:
My current project is a textmode interface (tvision) program
for a  LDA measurements. It comprises a GPIB interface, serial
ports, drives a traverse mechanism and preprocesses the results.
The debug version (including a debuggable tvision lib) has a size
of 2.405.361 Bytes. The stripped version reduces to 508.928 Bytes.

The original program from the manufacurer of the LDA setup was less
powerful,
more crash prone, written for MSC 5.0 or so had about the same size.

So, exe size is not too bad for a 32 Bit program. 

The original only ran with at least 540 kB DOS mem free, which is
quite a pain if you have the compiler on the local net.
