Building PostgreSQL 9.1.4 on Solaris 64-bit with gcc 4.6 - Mailing list pgsql-general

Hello,

I'm trying to build 64-bit PostgreSQL with gcc 4 on the solaris platform
- this worked fine with gcc3, but the error below seems to come up with
gcc4 .  has anyone seen it before (or does anyone have a quick solution
for it?)

gmake[3]: Entering directory
`/src/postgres/postgresql-9.1.4/contrib/dummy_seclabel'
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing
-fwrapv -fPIC -I. -I.  -c -o dummy_seclabel.o dummy_seclabel.c
dummy_seclabel.c:15:31: fatal error: commands/seclabel.h: No such file
or directory
compilation terminated.

Thanks
