It's a known issue. Patches to other packages will come later, to adapt them to the new API. To work around brokenness, there needs to be *two* different headers: 1. one to be used before including system headers, that maximizes visibility by enabling system-dependent feature test macros (that will be tested by system headers) 2. one to be used after including system headers, that performs preprocessor tests and defines. skalibs/nonposix.h is the first one. Previously, there was no second one, and the tests were scattered all over. There was a strnlen declaration in skalibs/posixplz.h (which serves a totally different function: declaring things that should be in POSIX, but *are not*, i.e. working around problems in the standard, instead of problems in systems failing to respect the standard), a build-time sysdep for error.h, #defines for MSG_NOSIGNAL, etc. etc. skalibs/posixishard.h now is the second one, and centralizes all the tests. As a result, the eproto sysdep is unnecessary and has been removed. skalibs/error.h is now a static header, it is not built anymore. 2014-09-18T18:55:44Z Laurent Bercot ska-skaware@skarnet.org 2014-09-18T18:55:44Z urn:sha1:3534b428629be185e096be99e3bd5fdfe32d5544
