В perl/pp.c есть такая странная конструкция:
38 /*
39 * Some BSDs and Cygwin default to POSIX math instead of IEEE.
40 * This switches them over to IEEE.
41 */
42 #if defined(LIBM_LIB_VERSION)
43 _LIB_VERSION_TYPE _LIB_VERSION = _IEEE_;
44 #endif
Символ _LIB_VERSION также определен в libm. Насколько я понимаю, эта
конструкция неправильная, поскольку не ясно, подцепит ли libm *этот*
_LIB_VERSION или нет. Надо было бы определять через extern, но тогда
возникает сложность, в каком месте его присваивать.
Нужно ли это всё для glibc, или glibc и так использует _IEEE_?
