Hello,

this suggestion works great! I modified RConfig.h, compiled and linked
again and tried benchmarks.C as well as some of my own root applications.
We'll probably need something like

#if defined(__linux) && !defined(__powerpc) && !defined(__egcs10x)

...

#endif

to pick the correct #defines for linux/egcs1.1 by default. To compile with
egcs1.0.x one would have to pass the flag -D__egcs10x to the compiler.

Thanks again! Stefan
