Here's a much easier way to reproduce the problem,
using only gnulib. The key is to test the string
module with another, like memchr:
$ ./gnulib-tool --test --with-tests string memchr
Here's the output I see:
In file included from ../../gltests/test-string-c++.cc:23:
../gllib/string.h:296: error: no matches converting function 'memchr' to type
'void* (*)(const void*, int, size_t)'
/usr/include/string.h:74: error: candidates are: void* memchr(void*, int,
size_t)
/usr/include/string.h:76: error: const void* memchr(const
void*, int, size_t)
../gllib/string.h:299: error: type of 'memchr' is unknown
../gllib/string.h:299: error: invalid type in declaration before ';' token
