The actual error message is quite explanatory
external/mesa/src/gallium/drivers/nouveau/codegen/nv50_ir_peephole.cpp:421:35:
*error: 'isfinite' was not declared in this scope*
Whereas which branch of the ifdef spaghetti the compiler takes in order
to get there is a good question. I doubt that I'll get the chance to
look into it any time soon. Yet it makes sense to use C++ headers for
C++ code - don't you agree ?
