Package: postgis
Version: 2.2.0+dfsg-3
Tags: patch
postgis fails to build because the testcases fail, e.g.:
https://buildd.debian.org/status/fetch.php?pkg=postgis&arch=hppa&ver=2.2.0%2Bdfsg-3&stamp=1451249930
specifically this test fails:
Suite: wkb_output
Test: test_wkb_out_point ...FAILED

CU_ASSERT_STRING_EQUAL(s,"00000000017FF80000000000007FF8000000000000")

The reason why this fails is, because parisc/hppa and mips have different
floating point representations for NAN (not-a-number).
The attached patch fixes it for hppa (tested!) and most likely for mips as well
(untested).
Can you apply this patch for the next upload and/or push it upstream ?
Thanks,
Helge
PS: For hppa postgis will probably still fail to build, but that's most likely
a problem in postgres not postgis (still working on it).
