Indeed, thanks for the correction.

And it turns out that it worked at some point (at least GCC 2.95.3):

gax% g++295 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -o pr14962 pr14962.c
gax% elfdump pr14962 | grep statvfs
      [13]  0x00020870 0x00000000  FUNC GLOB  D    0 UNDEF       statvfs64
      [69]  0x00020870 0x00000000  FUNC GLOB  D    0 UNDEF       statvfs64

so we have a regression.
