Error in freadahead

[Daniel G.]

Hello,
I'm trying to compile findutils-4.6.0 in my own customized operating
system. I'm using glibc-2.28 with gcc-8.2.0 and linux kernel 4.18.16.

I've got this:
freadahead.c:92:3: error: #error "Please port gnulib freadahead.c to your
platform! Look at the definition of fflush, fread, ungetc on your system,
then report this to bug-gnulib."
  #error "Please port gnulib freadahead.c to your platform! Look at the
definition of fflush, fread, ungetc on your system, then report this to
bug-gnulib."

That's why I'm reporting this error.

I would appreciate some information about how to fix this error, for
findutils, but also for other gnu applications that can be affected by this
error.

Thank you!
