-Wmultichar is enabled by default with GCC (but not clang). It is impossible to disable this warning with #pragma GCC diagnostic ignored. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431 While compiling, for example, minidump_file_writer.cc: In file included from ../../minidump/minidump_extensions.h:25:0, from ../../minidump/minidump_file_writer.h:27, from ../../minidump/minidump_file_writer.cc:15: ../../util/misc/pdb_structures.h:45:38: error: multi-character character constan t [-Werror=multichar] static const uint32_t kSignature = '01BN'; ^~~~~~ ../../util/misc/pdb_structures.h:106:38: error: multi-character character consta nt [-Werror=multichar] static const uint32_t kSignature = 'SDSR'; ^~~~~~ ../../minidump/minidump_file_writer.cc:190:23: error: multi-character character constant [-Werror=multichar] header_.Signature = MINIDUMP_SIGNATURE; ^~~~~~~~~~~~~~~~~~ doc/developing.md is also updated to provide GCC build instructions for Android.
