[GiNaC-list] problems with cstring and string

[Mario Prausa]

I think the option

   CLN_CFLAGS=-I$CLN/include/cln/

should read

   CLN_CFLAGS=-I$CLN/include/

All the CLN headers are referred to by "cln/...." in ginac. So you
should not specify this subdirectory.
Then the files "string.h" and "cln/string.h" shouldn't be confused anymore.
