Re: Compile error with xlclang++ on AIX

[Christian Biesinger]

That was actually the second error I got. I had to work around this
first one to get to it:

$ /opt/IBM/xlC/16.1.0/bin/xlclang++ test.cc -I gnulib/import -I
../gnulib/import/

Error while processing test.cc.

$ cat test.cc
#include "gnulib/config.h"
#include <stdlib.h>

int main() {
}
