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.
