LIMITS.cpp assumes integers with no padding bits
------------------------------------------------
Key: STDCXX-423
URL: https://issues.apache.org/jira/browse/STDCXX-423
Project: C++ Standard Library
Issue Type: Bug
Components: Configuration
Affects Versions: 4.1.2, 4.1.3, 4.2
Environment: unknown
Reporter: Martin Sebor
Priority: Trivial
The LIMITS.cpp config test tries to determine exact-width integer typese (the
equivalent of things such as int32_t) but it fails to consider the fact that
all integer types other than unsigned char may have padding bits that
contribute to their size but not to their range (i.e., there may be two or more
distinct bit patters that represent the same value, or bit patterns that do not
correspond to any value at all). This is only an issue in theory since we know
of no architecture with such a representation.
