Anything like #pragma warn "my message" in GCC?

[Mark Minich]

In some other compilers, I can output a message, warning,
or error from the preprocessor with one of the following
directives (which vary from one compiler to another):

#info "my message"
#warn "my message"
#error "my message"

or

#pragma info "my message"
#pragma warn "my message"
#pragma error "my message"

...or other similar syntax.

I tried various combinations of these, and I looked in the
online GNU manual under pragmas and preprocessor directives,
but I found nothing like these.

Is there a way to output messages, warnings, or force errors
and print associated messages, from the GCC preprocessor?

Thanks,
