Re: Netsurf build failure: 'PATH_MAX' undeclared (patch)
Hello Guillem,
Apologies for the late reply.
Many thanks for the thorough comments on the patch. I have tried to address the
issues that you pointed out in the attached new version of the patch.
For those interested in tracking this issue, I had file a bug report upstream
with the original patch:
https://bugs.netsurf-browser.org/mantis/view.php?if=2824
If there are no further comments, I will upload the new version of the patch to
that bug report.
Best regards,
João
