On mingw, I'm seeing this warning:
In file included from pipe-filter-ii.c:163:0:
pipe-filter-aux.h:75:0: warning: "read" redefined
#define read nonintr_read
In file included from ./fcntl.h:67:0,
from pipe-filter-ii.c:23:
./unistd.h:1785:0: note: this is the location of the previous definition
# define read rpl_read
This patch should fix the warning.
