FYI the original is here:

http://svnweb.freebsd.org/base/head/include/tgmath.h?view=markup

My changes were:

* The #ifdef log2 block (to avoid a redefinition warning)

* Reworded the GCC version check due to use of a FreeBSD-specific macro

* Double-underline prefixed all variables

* The !_LDBL_EQ_DBL section

* Commented out nexttoward()
