Sorry, my mistake, the Bessel functions are not a GCC extension but POSIX standard functions. http://pubs.opengroup.org/onlinepubs/9699919799/functions/j0.html Since TeX Live is always built on a POSIX platform (MSYS2 on Windows), you can expect j0 etc. to be available in LuaTeX.
That is true for the Bessel functions, but not for some other "-lmath" functions (such as the erf), so they may depend on the system. Alan
