Checking to see if your system supports struct statfs... Yes, it does. Checking to see if your struct statfs has f_flags field... No, it doesn't. Checking to see if your system supports static inline... Your compiler supports static __inline__. Checking how to access stdio streams by file descriptor number... I can't figure out how to access stdio streams by file descriptor number. strcoll() found. 2 comments: - no whitespace after the test output, in contrast to the other tests done by Configure (yes, unimportant in the extreme) - is it worth testing all alternatives ? this is unnecessary, but might provide a teensy bit more info wrt what compilers support which variations. mine likes "static __inline__" [jimc@groucho perl-git]$ gcc --version gcc (GCC) 4.4.4 20100630 (Red Hat 4.4.4-10) Copyright (C) 2010 Free Software Foundation, Inc.
