Well, hopefully not much - awk is defined by POSIX, after all.
gawk manpage mentions these extensions in description of --posix
flag:
              o \x escape sequences are not recognized.

              o Only space and tab act as field  separators  when
                FS is set to a single space, newline does not.

              o The  synonym func for the keyword function is not
                recognized.

              o The operators ** and **= cannot be used in  place
                of ^ and ^=.

              o The fflush() function is not available.

These should be pretty easy to deal with.
