Generic versions of `long double' math functions. * sysdeps/libm-ieee754/s_isinf.c [NO_LONG_DOUBLE]: Add string alias for __isinfl. * sysdeps/libm-ieee754/w_acoshl.c, sysdeps/libm-ieee754/w_acosl.c, sysdeps/libm-ieee754/w_asinl.c, sysdeps/libm-ieee754/w_atan2l.c, sysdeps/libm-ieee754/w_atanhl.c, sysdeps/libm-ieee754/w_cabsl.c, sysdeps/libm-ieee754/w_coshl.c, sysdeps/libm-ieee754/w_dreml.c, sysdeps/libm-ieee754/w_expl.c, sysdeps/libm-ieee754/w_fmodl.c, sysdeps/libm-ieee754/w_gammal.c, sysdeps/libm-ieee754/w_gammal_r.c, sysdeps/libm-ieee754/w_hypotl.c, sysdeps/libm-ieee754/w_j0l.c, sysdeps/libm-ieee754/w_j1l.c, sysdeps/libm-ieee754/w_jnl.c, sysdeps/libm-ieee754/w_lgammal.c, sysdeps/libm-ieee754/w_lgammal_r.c, sysdeps/libm-ieee754/w_log10l.c, sysdeps/libm-ieee754/w_logl.c, sysdeps/libm-ieee754/w_powl.c, sysdeps/libm-ieee754/w_remainderl.c, sysdeps/libm-ieee754/w_scalbl.c, sysdeps/libm-ieee754/w_sinhl.c, sysdeps/libm-ieee754/w_sqrtl.c: New files.

Reentrant version of getlogin function, specified in P1003.1c/D6. Stub version. * sysdeps/unix/getlogin.c (getlogin): Use ttyname_r instead of ttyname. This avoids saving and restoring the old content. Also use setutent_r, getutline_r and endutent_r instead of accing UTMP file directly. * sysdeps/unix/getlogin_r.c: New file. Reentrant version of getlogin function, specified in P1003.1c/D6. Tue Jun 4 20:10:09 1996 J.T. Conklin <jtc@cygnus.com> * sysdeps/libm-i387/s_finitef.S: Fix mask for exponent. * elf/dl-lookup.c (_dl_lookup_symbol): Grok magical undefined symbols _GNU_libc_dl_{open,close,symbol} and resolve them to dl functions. * elf/rtld.c (rtld_map): Renamed to _dl_rtld_map, made global. * elf/link.h: Declare _dl_rtld_map. * elf/dl-lookup.c (_dl_symbol_value): New function. * elf/link.h: Declare it. stdio-common/vfscanf.c: Prepare for reentrant libio. Used in reentrant libio.
