Hmmm, there are more strange things about that. When I just compile

  cc -s -Ipostgres/include circle.c 

and then

  os:/work/plewe[20] spog
  Warning: Assuming database plewe
  connected to backend database plewe
  spog > load "/work/plewe/circle.o"
  FATAL: no response from backend: detected in PQexec
  spog: detected a fatal error, exiting...
  os:/work/plewe[21] 


You see?

When I now do a dummy linker run, e.g.

  ld -o foo.o circle.o

then I get

  os:/work/plewe[21] spog 
  connected to backend database plewe
  spog > load "/work/plewe/foo.o"
  LOAD successful


The difference between circle.o and foo.o is that foo.o seems to
be better prepared for dynamic loading, unless I do not understand
the mechanisms.

  os:/work/plewe[23] nm circle.o
           U _atof
  00000000 T _circle_in
  000001ac T _circle_out
           U _palloc
           U _point_dt
  00000240 T _pt_in_circle
           U _sprintf


  os:/work/plewe[22] nm foo.o
  00002000 d __DYNAMIC
  00000020 T _circle_in
  000001cc T _circle_out
  00002090 D _edata
  00002090 B _end
  000004a0 T _etext
  00000260 T _pt_in_circle
  00000020 t circle.o


Ah, my system is SunOS4.1.3 and Postgres 4.2.

Remaining strange, Joerg
