Subject: [PATCH 1/2] [libc] force GCC limits.h to not include_next limits.h
Who defines what the width and thus the min/max values for a given integer
type? We'd like to rely on the compiler's resource dir's definitions, but GCC's
limits.h can end up using include_next to include limits.h from GLIBC.
This results in build failures with GCC due to __GLIBC_USE being undefined (a
feature detection macro defined only relevant to glibc). We'd like to avoid
the compiler pulling in the libc's headers (unless there's some critical reason
why, which we don't have today AFAIK). GCC's limits.h will avoid this circular
includes if _LIBC_LIMITS_H_ is defined.
GCC's limits.h only defines LLONG_MAX, LLONG_MIN, and ULLONG_MAX if
__STDC_VERSION__ is defined and >= 199901L, i.e. not for C++, so provide those
definitions ourselves.
Due to this, we should never be including <limits.h> in libc/ (other than in
CPP/limits.h). Sources and tests should be including
"libc/src/__support/CPP/limits.h" in place of <limits.h>.
