I'm attempting to build coda-5.0.1 source on a linux 2.2.1 kernel system
using libc5 libraries. I get identical errors using gcc-2.7.2.3 and
egcs-1.1.1 . First it couldn't seem to find readline.h where its installed
in /usr/local/include/readline/readline.h . So I simply hardcoded to the
path in the #include for readline.h in parser.c . That fixed that...but
then I developed this error,

I can't seem to find MAP_FAILED on any of my system header files, so I'm
not exactly sure how to resolve the problem. Am I missing a header file
someplace or doing something else wrong. Any help is appreciated.
