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.
Reproducible: Sometimes
