Bug ID: 65128
Summary: remove "linux" and "unix" from preprocessor macros
from cpp-5
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: shawn at churchofgit dot com
I just spent like a whole hour until I realized that cpp defines "linux" which
gives this confusing error:
src/systemctl/bootspec.h:40:15: error: expected identifier or ‘(’ before
numeric constant
char *linux;
^
We should remove these defines from gcc 5, and force programs to check __unix__
and __linux__

They are indeed legacy defines. More affected systems:
dragonfly.h: builtin_define_std ("unix"); \
freebsd-spec.h: builtin_define_std ("unix");
\
gnu.h: builtin_define_std ("unix"); \
kfreebsd-gnu.h: builtin_define_std ("unix"); \
knetbsd-gnu.h: builtin_define_std ("unix"); \
kopensolaris-gnu.h: builtin_define_std ("unix"); \
linux.h: builtin_define_std ("linux"); \
linux.h: builtin_define_std ("unix"); \
sol2.h: builtin_define_std ("unix"); \
sol2.h: builtin_define_std ("sun"); \
