In particular, I’ve been trying to build iperf using RTEMS tools for the ARM Cortex-A9 (targeting a Zynq based eval board), but am not getting very far.  The compile dies on lacking a definition for the int64_t type, which the code expects to find by including <sys/types.h>, amongst other things.  I am struggling with what might be the “right” way to address this.  Do you have any suggestions?

stdint.h
