[fedora-india] missing stropts.h

I want to compile the the source code given in a well known unix programming book(stevens) .I downloaded the codes but unable to build it ,giving me an error error: stropts.h: No such file or directory I don't know what to do.... I am using fedora 11 latest gcc in the system. I also try to include the search path which include a file -I./usr/include/xulrunner-sdk-1.9.1/system_wrappers but it does not help . I open the header file and the definition is there #include_next<strops.h> so ultimately there is not the original file... any one please help.. -- Hirak Sarkar CSE 3rd year Kalyani Govt. Engg.
