If chdir is a problem, why not using a heavy weight approach (better safe
than sorry particularly if gnulib is used for a lot of project):
- fork and exec an helper for name resolution
- pass fd using a socket
It is really heavy but it is on the safe side

Hi Bruno
OK, a couple of problems:
During compile of gllib:
NSIG missing, I added it to gllib/spwani.c, in a brute force fashion (#define
NSIG 32) without really know what I'm doing here...
/bin/kill -l | wc -w returns 33.

Hi Paul,
For example, if save_cwd called
currdir_fd = open (.);
then on a platform that supports fchdir() natively [not gnulib's
emulation], a failure to do fchdir (currdir_fd) is of type (a).
It can only occur if some other part of the program did side
effects on currdir_fd.

Hi Bruno
OK, the highest number for any SIGsomething is 31, so NSIG should really be
32.
The only SA_something Macros I can find are SA_DATA_SITE in sys/socket.h,
most probably unrated, and SA_NOCLDSTOP and SA_RESERVED_31 in signal.h, and
nothing that looks remotely like a replacement,
Oh well, it is not here. So some kind of workaround is needed.

Good question. In config.h I can only see:
#define HOST_NAME_MAX
So it gets #define'd but with no value
From config.log:
configure:33394: checking for HOST_NAME_MAX
configure:33420: cc -o conftest -g -I/usr/local/include conftest.c 5
static long int longval () { return MAXHOSTNAMELEN; }

Yes, but with a condition that apparently is not met (and to deeply nested and
complicated for me to grasp), hence my change:

Hi Bruno
test-stdio-c++.o was the empty file
gllig/printf.o is not, but does not contain rpl_printf:
$ nm -Pe gllib/printf.o
E __stdio_fp
F printf
E rpl_vfprintf

You mean add alphasort to gllib/dirent.in.h?
We don't have an alphasort elsewhere
And yes, we're quite a bit behind the current POSIX...

Libfloss is not used (yet?), but has some hooks for this problem, the compiler
wrapper script it contains uses -DSOCKLEN_T=socklen_t.
Other than that socklen_t is typedef'ed in sys/socket.h (and as an int) but,
for some strange and probably historical reason, not used anywhere, in
