That probably means that the program you are trying to port uses some 
non-ANSI features (like header files and library functions which ANSI 
doesn't mention).  Strict ANSI C code will compile on any ANSI-compliant 
compiler without any problems (and in my experience, it does).  
Unfortunately, too few people restrict themselves to ANSI C when they 
write programs...
