[svn-r20894] Purpose:
Updates configure definitions on linux.
Description:
We only define _POSIX_SOURCE which only allows for the lowest level of
POSIX support (IEEE 1003.1), which is unsuitable for clock_gettime() functionality on modern linux systems. This symbol was changed to _POSIX_C_SOURCE=199506L, which gives the 1996 version of POSIX support and allows clock_gettime() and CLOCK_MONOTONIC to be found.
We do not link to the BSD compatibility library, even though we define
_BSD_SOURCE. -lbsd-compat was added to AM_LDFLAGS in accordance with GNU
recommendations. This does not appear to change anything in the current
library.
Tested on:
jam(linux32-LE) This was tested with various configure settings including
parallel, threadsafe, C++ and FORTRAN enabled.
