Comment (by Jörg Krause <joerg.krause@…>):

 No, I am on revision `c0fb4b1c21865d2096fbee2f3c77026f5a743180`.

 Sorry, the macro definitions I posted are wrong. This is the correct ones:

 * `BOOST_NO_FENV_H` ''is not defined''
 * `BOOST_TEST_FPE_SUPPORT_WITH_GLIBC_EXTENSIONS__` ''is defined''

 Note, this is the content of output/host/opt/ext-toolchain/sh4-buildroot-
 linux-uclibc/include/c++/5.4.0/fenv.h:
