Bugzilla Bug 198774

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

confirmed here, using -j1 it compiles fine

ehrrr... same issue still with 1.1

Fixed in 1.1 CVS.
