x86 arch lacks inb_p and outb_p inline functions. This is required for memtest86+. I don't know how properly make an assembly here, so when making memtest I copied sys/io.h into local directory, and copied these functions from uClibc. I attach modified header for reference (they should go into bits/io.h). -- http://lynxlynx.tk/ Power electronics made simple Unix and simple KISS C code
