following other people’s suggestions, I am trying to replace
gcc with qcc, g++ with QCC, while trying other open source projects.
Sometimes, I get those warnings:
cc: badly formed -W option, ignoring
Here is a test case:
bash-2.05a$ gcc -W -c test.c
bash-2.05a$ qcc -W -c test.c
cc: badly formed -W option, ignoring

For cc & qcc, -W is the pass-through command, allowing you to pass
an option through to one of the underlying phases of the compilation.
e.g.
-Wl,-s says to pass -s through to the linker phase.
What did the -W option do under gcc?

-W turns on an extra set of warnings; different than -Wall.
Frank, you want to use qcc’s -Wc option to send the -W to the compiler,
like this:
-Wc,-W
I had to do something similar since qcc doesn’t support gcc’s -m* suite
of options; I needed this for my PPC compiles:
-Wc,-mstrict-align
HTH…
