[ Andreas Henriksson ]
* Bump python:any build-dependency to >= 2.7.5-5~ (Closes: #747928)
[ Emilio Pozuelo Monfort ]
* Use the default compiler on sparc, since it's already >> 4.7.
Closes: #751313.
[ Iain Lane ]
* 0001-Prevent-an-invalid-CARBON_LIBS-from-appearing-in-the.patch:
Cherry-pick patch from upstream to fix an invalid "@CARBON_LIBS@" token
appearing in Libs.private in the pcfile. (LP: #1330033)

# glib_micro_version += 1;
17
# glib_interface_age += 1;

19
# if any functions have been added, set glib_interface_age to 0.

# if backwards compatibility has been broken,

# set glib_binary_age _and_ glib_interface_age to 0.

dnl ************************
2303
2304
dnl We need to decide at configure time if GLib will use real atomic
2305
dnl operations ("lock free") or emulated ones with a mutex. This is
2306
dnl because we must put this information in glibconfig.h so we know if
2307
dnl it is safe or not to inline using compiler intrinsics directly from
2308
dnl the header.
2309
dnl
2310
dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2311
dnl user is interested in knowing if they can use the atomic ops across
2312
dnl processes.
2313
dnl
2314
dnl We can currently support the atomic ops natively when building GLib
2315
dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2316
dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2317
dnl we are using GCC (and not mingw*).
2318
dnl
2319
dnl Note that the atomic ops are only available with GCC on x86 when
2320
dnl using -march=i486 or higher. If we detect that the atomic ops are
2321
dnl not available but would be available given the right flags, we want
2322
dnl to abort and advise the user to fix their CFLAGS. It's better to do
2323
dnl that then to silently fall back on emulated atomic ops just because
2324
dnl the user had the wrong build environment.
2325
2326
dnl We may add other compilers here in the future...
