Dear Wolfgang,

sorry for not coming back to you. I had meant to track down the problem,
but was too busy during the past month. Not having used the standard string
class before turned out to be fatal to my motivation to follow the string
ramifications. Actually, I am equipped with too many string header files!
My system is a mixture between Mandrake 8.0, 8.1 and Cooker; gcc and the
standard c++ library in particular are from Cooker. The following header
files look most promising:

>From the package kernel-headers-2.4.3-20mdk:

>From the package glibc-devel-2.2.4-8mdk:

>From the package libstdc++3.0-devel-3.0.2-1mdk:

I guess the very last file is the crucial one; unless _CPP_STRING is defined
(how would one know?), it includes bits/std_string.h, which itself
triggers a cascade of inclusions (unless other symbols are defined).

It would surprise me if these observations were of much help, but maybe
they are not completely useless...
