I'v having a hard time convincing make to generate errcodes.h before
compiling any .c file that includes postgres.h. The only way I found was
to make src/include/errcodes.h a dependancy of the all target.
For instance, I tried to copy the way we generate fmgroids.h and it
turned out that it doesn't work (it tries to compile things in src/port
before entering src/include, and things in src/port include postgres.h).
