Also, 'icc' is Intel's C compiler. To pick up the Intel C++ compiler, the project might want to add a case for 'icpc'.

Please see http://uclibc.org/developing#contrib

As for using a C++ compiler, NAK.
Given how icc behaved last time i tried, thinking about piping our C-code through icpc and expecting any non-error output is just not realistic.

Anyway. Please submit proper patches if you want them to be applied.
TIA and cheers,
