It would be great if you provide function names. | I assume you are pointing to function names in localtime.c? Yes, those. | Do you mean the _rz functions? Yes, and tzalloc() and one or two which are just _z ... if it has a 'z' suffix in there somewhere, then it is relevant. The 'z' implies that it has a timezone_t as a parameter (which tzalloc() makes from a TZ string). Oh, there's also tzfree() of course - the inverse of tzalloc(). | But then NETBSD_INSPIRED need to be defined Notice just "inspired" not required... I suspect (without actually going to check) that essentially all you get with thet symbol defined will be the ones that you need. | (no problem, but may result in another porting issues for me on MS-Windows). There should not be a lot, and I cannot think of anything of a different nature than you have seen already. One issue may be the 'r' suffix part (thread safe) - but I assume windows has some way to make threaded programs, and hence to make thread safe library functions. kre
