No.  "strip foo.exe" (note: no -s switch to strip) is actually _more_
than just leaving out -ggdb3.  -ggdb3 adds line number and other
source-related information, but a minimal set of information about
symbols is put into the binary even without -g.  `strip' removes _all_
of the symbolic info, leaving just the bare machine code.

For example, without -ggdb3 you should still be able to run SYMIFY and
get at least the functions' names from the addresses.  After `strip',
this is impossible.
