This test makes sure that flang's runtime does not depend on the C++ runtime
library. It tries to link this simple file against libFortranRuntime.a with
a C compiler.
REQUIRES: c-compiler
RUN: %cc -std=c99 %s -I%include %libruntime %libdecimal -lm -o /dev/null

Manually add declarations for the runtime functions that we want to make sure
we're testing. We can't include any headers directly since they likely contain
