Apply __{BEGIN,END}_HIDDEN_DECLS to gdtoa{,imp}.h, hiding the arch-specific __strtorx, __ULtox_D2A, __strtorQ, __ULtoQ_D2A symbols. avoid left shift overflow in reallocarray. 2014-12-08T03:45:00+00:00 bcook 2014-12-08T03:45:00+00:00 urn:sha1:c2309f70a1d7d69c81f79e5ab9ad79e63d4d8e82 Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting 1UL 32-bits to the left causes an overflow. This replaces the constant 1UL with (size_t)1 so that we get the correct constant size for the platform. discussed with tedu@ & deraadt@ move reallocarray() to a seperate file so that -portable applications 2014-05-08T21:43:49+00:00 deraadt 2014-05-08T21:43:49+00:00 urn:sha1:d5f0005a9be9ae9d9f5d3cca531533e152bf50eb can avoid reinventing the wheel ok guenther schwarze
