Bug#888398: mblaze: FTBFS on hurd-i386: PATH_MAX undeclared

Source: mblaze
Version: 0.2-1
Severity: important
Tags: upstream
Justification: fails to build from source
User: debian-hurd@lists.debian.org
Usertags: hurd

The build of mblaze for hurd-i386 (admittedly not a release
architecture) failed with multiple errors of the form

  seq.c:21:19: error: 'PATH_MAX' undeclared (first use in this function); did you mean 'INT8_MAX'?

as detailed in [1].  The Hurd notoriously has no static PATH_MAX.
Best practice is dynamically accommodating whatever you actually
encounter, since fixed-size buffers generally run the risk of either
wasting memory or yielding truncation (or, worse, buffer overflows).
However, if that's infeasible, you can also look up _PC_PATH_MAX via
pathconf or even supply a fallback constant (traditionally 4096).

Could you please take a look?
