I can not figure out how to report a bug to perl ... but you for sure.

In file Errno_pm.PL​: line 135 it should be​:

135​: my ($linux_errno_h) = grep { -e $_ } map { "$_/asm/errno.h" }

Linux has its errno.h in asm/errno.h else you get an error that it could not be
found.

I don't know enough about Linux header files to agree or disagree with your main point, but I note that on my Ubuntu Linux machine, there is no /usr/include/asm directory​:

#####
$ !11
find /usr/include -type f -name 'errno.h' | xargs ls -l
-rw-r--r-- 1 root root 5585 Jan 6 19​:27 /usr/include/asm-generic/errno.h
-rw-r--r-- 1 root root 2367 Nov 16 17​:43 /usr/include/errno.h

Yes, include linux/errno.h, it includes asm/errno.h and nothing else on a 32 bit
linux !

Which linux distribution are you running?

Both debian​:

tony@​mars​:.../docs/perl5$ cat /etc/debian_version
8.7
tony@​mars​:.../docs/perl5$ ls -l /usr/include/errno.h
-rw-r--r-- 1 root root 2367 Nov 28 15​:22 /usr/include/errno.h

and Redhat derived​:

$ cat /etc/redhat-release
CentOS release 6.6 (Final)
$ ls -l /usr/include/errno.h
-rw-r--r-- 1 root root 2452 May 10 2016 /usr/include/errno.h

have errno.h in the places we look.

I suspect we should be searching libpth as well as loclibpth.

Or use the output of

echo "#include <errno.h>"|cc -E -|awk '/^# [1-9]* "\//{print $3}'|sort -u

or its moral equivalent, modulo portability concerns.

Given that the OP has failed to respond showing what distribution is in
use, and what location(s) errno.h can be found at one that distribution,
I'm marking this ticket as rejected.
