用于嵌入式Linux系统的标准C的库函数

/ The SCO signal stuff seems to be weird.  The POSIX stuff appears to
/ "extended" system calls, and use values in eax and edx.
/ Like most of the other signal routines, it takes a function pointer
/ in %edx.  Since this function is terribly small, I am including it
/ in all of the ones that need it, for now at least.  Seems silly to include
/ a whole file for two instructions.
