This is the data on the binary:

With g++ 2.95.2 with libstdc++
[larsbj@lett stdc++]# ls -l src/lyx src/lyx-stripped
-rwxrwxr-x   1 larsbj   larsbj   43349198 Dec  2 04:15 src/lyx
-rwxrwxr-x   1 larsbj   larsbj    3250272 Dec  2 14:15 src/lyx-stripped    
[larsbj@lett stdc++]$ size src/lyx
   text    data     bss     dec     hex filename
2329518  911792   66652 3307962  3279ba src/lyx         

Without g++ 2.95.2 without libstdc++
[root@lett build]# ls -l src/lyx src/lyx-stripped
-rwxrwxr-x   1 larsbj   larsbj   10241000 Dec  2 14:44 src/lyx
-rwxrwxr-x   1 larsbj   larsbj    1796116 Dec  2 14:44 src/lyx-stripped
[larsbj@lett build]$ size src/lyx
   text    data     bss     dec     hex filename
1489827  297220   61000 1848047  1c32ef src/lyx

This has been compiled with:

g++ -g -O -fpermissive

Ad. compilation. When compiling with libstdc++ the mem used by
the compiler is approx. 2-5 times larger than when compiling without.
The compilation speed is also a lot slower.

Execution speed seems to be about the same, with libstdc++ perhaps
being slightly faster.

I have not tested much, but have so far not seen any strange
bahaviour.

Also note that LyX does not excercise the library a lot, it uses
string and vector fairly heavy.
