functexcept.cc draws in everything

[Henning.Baldersheim@devoll.no]

Well, I learn something every day.

I checked it out and I found that I was using -Wl,--gc-sections. But that 
should in theory work, but it did not.
Code was 230K before I did anything.
Splitting up functexcept.cc made it down to 116K.
Enabling multilibs with fexceptions/fno-exceptions brought and linking with 
-fno-exceptions took it down to 90K.

I checked info gcc/ld and found that -ffunction-sections and perhaps 
-fdata-sections should be enabled to. In my code and in the ecos code it is 
enabled.
But I could not see any trace of it for the build of libstdc++. What is the 
default ?
I guess that if I enable it it should work fine then.
