Looks like they are related. Adding '%option noyywrap' to lexxer.l 
results in an incorrect mig binary which finds syntax errors where 
there are none. The solution is to use the Debian source package 
mig-1.3.1.99, avoid the 'autoreconf --install' and use the provided 
configure script. Configure script tests for -lfl but does not require 
it; it should. (On Fedora the solution is the installation of package 
flex-devel) With libfl present the linker succeeds. Also the Mach build 
fails on Fedora with the correct mig binary if not all glibc packages 
(glibc*) are present.
