Using some of the operators and routines in the standard prelude lead to a dependency on standard system math routines, usually available in libm. This is the case for sin, cos, etc. If no such operator/routine is used by the user program, however, the dependency should not be there. We recently implemented some parts of libga68 in Algol 68, and these use the entier operator. Using this operator drags in a dependency on floor, floorf and floorl via some GCC built-ins. This patch adds the gnulib implementation of floor, floorl and floorf to libga68. Tested in x86_64-pc-linux-gnu, in both -m64 and -m32 modes. Tested in i686-pc-linux-gnu. Signed-off-by: Jose E. Marchesi <jemarch@gnu.org> libga68/ChangeLog * ga68-math.c: New file. * floor.c: Imported from gnulib. * configure.ac: Do not check for libm. * Makefile.am (libga68_la_SOURCES): Add ga68-match.c. * Makefile.in (am_libga68_la_OBJECTS): Regenerate. * configure (ac_res): Likewise.
