I don't see a reason to get it vendor imported for few reasons: 1. it's only one file (src/lib/libc/stdlib/strtod.c). Maybe we need to think to take few more like strtof(), but I not sure in full and generalized versions compatibility. Need testing. Most of other stuff is not supposed to work on IEEE arifmetic machines or not standard (not included to POSIX, SuS or C99). Correct me if I wrong. 2. we'll have to change it (at least for adding new definitions of arches). Vendor's version is supposed to work on i8087, m86k, vax, ibm and cray arches. 3. And according of "much soon than us": All problems that Bruce mentioned are not problems, just style improvements. And last I think difference in slow reaction on addition of new features/imporovement to Netlib (merging them to FreeBSD) is more result of lack of interest to such complicated (and already working!) code. So, let me some time and then you'll see "request for review", please give comments. Even (1) is enough to understand that vendor import is just overhead because file will be taken out of vendor branch as soon as powerpc and sparc64 arches comes to "make world" as it already has been done for alpha and ia64.
