With MAKEOPTS="-j3" I have: gcc -DPATH_RADVD_CONF=\"/etc/radvd.conf\" -DPATH_RADVD_LOG=\"/var/log/radvd.log\" -DLOG_FACILITY=LOG_DAEMON -DPATH_RADVD_PID=\"/var/run/radvd/radvd.pid\" -DVERSION=\"1.0\" -DINET6=1 -I. -I. -pipe -O2 -march=nocona -Wall -Wpointer-arith -Wcast-qual -Wcast-align -Wconversion -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -c scanner.c scanner.l:20:18: error: gram.h: No such file or directory scanner.l: In function 'yylex': scanner.l:44: error: 'T_INTERFACE' undeclared (first use in this function) ...and many error below... I suppose gram.h was unfortunately generated after gcc tries to search it. With forced MAKEOPTS="-j1" all is happy.

confirmed here, using -j1 it compiles fine
ehrrr... same issue still with 1.1
Fixed in 1.1 CVS.
