The change is good if only for this sole reason. Private libraries still conflict with the same library installed by other means, in the single process image. That said, if you do development directly on the tiny platforms, the remote gdb server is probably better solution than the local gdb. Also, WITH_SHARED_TOOLCHAIN probably would give you much bigger savings both in disk space and used memory than libreadline and libgnuregex. I just abandoned a hope to flip this knob. --8yXJwKnNP0rurr9c Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJTvYmhAAoJEJDCuSvBvK1BHpoP/iotJ2yg8lzfIjdkyz9bWNcQ KtITXvDSENO9sdUf1Gc29R4lRHD7BEZjaI7C37DaafkV2AL5taHltT++NqKmSC4U fEzyTv2c9Aau8V+nv0wp2zxWLq7dkMAY/5GDkzlT9JeATJ3ROfX6T5Wb19fAp6Nb sEOSVv5wRQNMEkikNAX6Lq7RMJVL+XRt9nOOiriCDwid/xaWZE89uh3+wLmm5olm QWcYCuC3OMNwP1Ee+qbk+Wy5l67xwXuq1a3hazydpldKEubs0cwcqOcP21K6pNFH A6EKfLQkty4YuJyjFTKDjW2HTYr3gAzmo58GGXNZ0wV2PYXux5h7nEgXcd2HF+vF sn4oTnFDTxU8AtxjStjsmuaRyicVS/ldEoHxAE4TM1NSM+nI199LxMKxSYxkuqwg 8y0QxL22fc2XTHxAHPVjMPJ6/uLeDK5+pEDBGRlGES1Kn4IjATw9mvTOOWJaKpqv 5qe3rdoDvCCs/aLZU5Y5EeEihN7yEvzyjAhQF0ZNaslMsMv2ovLVmTeqXiIjokuk GYJJ2i4IeZRUcig0g9zMSFlpUSeMZZzXMAeDyFVa6x2WOvdQ+3v3OAc/2tKlwbat 4nOdcfkbtnC6hb7/mAI4dnjQVtXiiHOCZ1N4OAywt0Lhzh8ZzOnrq0eWlxIjHJWK 5sdQs1/F4Hn4Z9F73Km9 =nA8P -----END PGP SIGNATURE----- --8yXJwKnNP0rurr9c--
