i don't know what happened, but it seems like a char*. my system is a
debian i636 etch, here are compiler versions:

$ gcc-4.3-exp -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ./configure --program-suffix=-4.3-exp
Thread model: posix
gcc version 4.3.0 20070914 (experimental) (GCC)

gives 'warning: deprecated conversion from string constant to âchar*â'



$ gcc-4.2 -v
Using built-in specs.

gives the same warning
