Source: casacore
Version: 2.1.0-2
Severity: important
Justification: fails to build from source
Thanks for looking into my previous reports.
Alas, builds of casacore on PowerPC variants (powerpc and ppc64el, and
the non-release ppc64 architecture) are now failing:

AFAICT, the issue is that, on these architectures, g++ in strict
-std=c++11 mode doesn't predefine __linux, just __linux__, so
aipsenv.h leaves AIPS_LINUX undefined and HostInfo.cc falls back on
stubs that don't match HostInfo.h's prototypes. (FWIW, there's no
such problem in -std=gnu++11 mode.)
Could you please take a look?
Thanks!
