That's not the only problem AFAICS:

/usr/include/sys/resource.h: At global scope:
/usr/include/sys/resource.h:79:25: error: declaration does not declare 
anything [-fpermissive]

/homes/botcazou/gcc-head/src/gcc/system.h:469:48: error: 'char* strstr(const 
char*, const char*)' conflicts with previous using declaration 'const char* 
std::strstr(const char*, const char*)'

and so on.  It's SPARC/Solaris 10.

Yes, I can change that, but it's probably not the only case.
