I ran into this issue doing a very bog-standard build of the newly released GCC
12.1 on linux X86-64, using a configuration that previously successfully built
GCC '12.0.1 20220424 (experimental)' a week or so ago.
I did not save the output from the failed build, but it would eventually fail
with 'error: 'fenv_t' has not been declared in '::' ... '
For reasons that I'll skip, between the successful build of 12.0.1 and now I
had added:
export
CPLUS_INCLUDE_PATH=/opt/local/include/c++/12.0.1:/opt/local/include/c++/12.0.1/x86_64-linux-gnu/
to my .bashrc
Removing the 'CPLUS_INCLUDE_PATH' environment variable made the problem go
away.
