[uClibc]getresuid and getresgid

[andy preston]

I'm trying to compile rdesktop for arm using uClibc 0.9.15. I'm getting
a linker error in libX11.so for getresuid and getresgid. Are these
functions that are meant to be supplied from uClibc ? Are they a
conditional based on something in Config.h ? 

Just trying to narrow down where the error is, linker order, unsupported
functions, conditional etc.

thanks,

Andy
