  Not exactly, to be precise the Amaya includes do a braindead remapping
of memcopy and memmove to bcopy. Bcopy is a void function, and this
break macros in the includes of linux which assume (rightly) that memmove
returns an int. There used to be a memcpy() detection in autoconf for
amaya but it seems to have been removed, leading to the fact that HAVE_MEMCPY
is no more defined, etc ...
  The correct way to fix this is to apply the following patch and
restore the memcpy detection in automake:

*** thotlib/include/sysdep.h    1999/03/10 13:00:26     1.13
--- thotlib/include/sysdep.h    1999/06/25 12:21:50
*************** extern volatile noshare int errno;      /* no
*** 1002,1009 ****
--- 1002,1011 ----
  #define strrchr rindex
  #endif
  #if !defined(HAVE_MEMCPY) && !defined(WWW_MSWINDOWS)
+ #if !defined __GNUC__ || __GNUC__ < 2
  #define memcpy(d, s, n) bcopy((s), (d), (n))
  #define memmove(d, s, n) bcopy((s), (d), (n))
+ #endif
  #endif

  /* Standard headers */

  It's included in the source RPM for amaya-2.1 available at
   ftp://rpmfind.net/pub/amaya/

and unless you really want to developp code in the amaya framework, I suggest
to stick with the RPMs on RedHat
