 To build the library and related programs, type @code{make}.  This will
 produce a lot of output, some of which may look like errors from
 @code{make} (but isn't).  Look for error messages from @code{make}
 containing @samp{***}.  Those indicate that something is really wrong.
 
+The compilation process takes several hours even on fast hardware;
+expect at least two hours for the default configuration on i586 for
+Linux.  For Hurd times are much longer.  All current releases of GCC
+have a problem which causes them to take several minutes to compile
+certain files in the iconvdata directory.  Do not panic if the compiler
+appears to hang.

 To build and run some test programs which exercise some of the library
 facilities, type @code{make check}.  This will produce several files
 with names like @file{@var{program}.out}.
