#11756: boost.Test: non standards compliant use of FE_* macros (unable to compile
boost test library on FPU-less arches)
----------------------------------+------------------------
Reporter: bartosz.krasinski@⦠| Owner: renficiaud

Milestone: Boost 1.64.0 | Component: test
Version: Boost 1.59.0 | Severity: Problem
Resolution: | Keywords:
----------------------------------+------------------------
Comment (by Jörg Krause):
We recently bumped the boost version from 1.61.0 to 1.63.0 in Buildroot.
Now, we get build errors for two architectures which were compiling
successfully before: SH4 and OR1K. Both use a uclibc-toolchain.

I've checked out the branch `topic/11756-non-standards-fpexception-intel`
of the test module, it does not build either.
At least, the SH4 toolchain does not have fenv.h. I did not checked to
OR1K toolchain, yet.
Here are some macros I've checked using the branch 11756:
* `BOOST_NO_FENV_H` ''is defined''
* `BOOST_SEH_BASED_SIGNAL_HANDLING` ''is not defined''
* `BOOST_TEST_FPE_SUPPORT_WITH_GLIBC_EXTENSIONS__` ''is defined''
