 Yes, it still affects the current versions.  G++ by default uses the
 shared version of libgcc.  It has a hardcoded dependence on the shared
 non-profiled version of libc.  So, when you compile and link with
 "-p" or "-pg", the linking process resolves libc routines from the
 non-profiled version of libc.  This also would be an issue if any
 other shared library with a dependence on libc was linked into the
 application.
 
 The simplest work around is for the user to link with -static when
 using -p or -pg.  I had debated a doc update but haven't done it.
