_GL_CXXALIAS_SYS (raise, int, (int sig)); in signal.h may give complie error in C++ source.

[Tatsuro MATSUOKA]

In the bug tracker octave, in which gnulib components are used,
_GL_CXXALIAS_SYS (raise, int, (int sig)); in signal.h seems to give compile
error.

https://savannah.gnu.org/bugs/?34378

John W. Eaton said in comment #3 in the above tracker that

*********************************************
I'm fairly sure this is a bug in gnulib, so needs to be fixed there. There
shouldn't be two 

_GL_CXXALIAS_SYS (raise, int, (int sig));

lines in the libgnu/signal.h file, or if there are, they should be fixed so
that they don't conflict. But in any case, that's something for the gnulib
developers to fix.
*********************************************

I have comment out one of
_GL_CXXALIAS_SYS (raise, int, (int sig));
lines compile error was disappeared.
