Sorry, that should be:

cc -c example.c
cc -e example -o example example.o

since -lc is implied by using cc.

I would think that
cc -c example.c
cc -e example -o example example.o -lc

would work just as well. It's not doing it in one step that matters,
but rather that cc provides the correct default options to ld.

The mystery is solved, thanks to Thomas Braunbeck, AS Software Service
AIX, Germany.

Compiling and linking the program with the one statement:

cc -O -e bug -o bug bug.c -lm

removes the problem and IDL's complaints. This should be changed in the
IDL documentation "Using CALL_EXTERNAL and LINKIMAGE on the IBM Risc
System 6000".

< cc -c example.c
< ld -e example -o example example.o -lc
