Hi,

I had a similar problem with gcc 4.5.2 and fixed it as follows.

Additionally, I build staprun for an ARM target with
arm-unknown-linux-gnueabi-gcc (crosstool-NG 1.12.1 - buildroot 2011.08) 4.4=
.3.
Here I need an additional patch.

Hack: std::string is missing.

Provide std::string as part of util.h as it missing in string.h.
