This patch makes the exeception specifier of libiberty's 'asprintf'
|
|
and 'vasprintf' declarations match those of glibc to work around the
|
|
problem described at <https://gcc.gnu.org/ml/gcc-help/2016-04/msg00039.html>.
|
|
|
|
The problem in part stems from the fact that libiberty is configured
|
|
without _GNU_SOURCE (thus, it sets HAVE_DECL_ASPRINTF to 0), whereas libcc1
|
|
is configured and built with _GNU_SOURCE, hence the conflicting declarations.
