Bug#913213: libclang-common-7-dev: /usr/lib/llvm-7/lib/clang/7.0.1/include/limits.h is invalid (nbsp character)

[Vincent Lefevre]

Package: libclang-common-7-dev
Version: 1:7.0.1~+rc2-1
Severity: grave
Tags: upstream
Forwarded: https://bugs.llvm.org/show_bug.cgi?id=39585
Justification: renders package unusable

/usr/lib/llvm-7/lib/clang/7.0.1/include/limits.h contains

#if !defined(__CLANG_LIMITS_H) || !defined(_LIBC_LIMITS_H_)

where the character after "||" is a no-break space (U+00A0).

This yields the following failure:

$ echo '#include <limits.h>' | clang-7 -E -
In file included from <stdin>:1:
/usr/lib/llvm-7/lib/clang/7.0.1/include/limits.h:25:34: error: invalid token at
      start of a preprocessor expression
#if !defined(__CLANG_LIMITS_H) || !defined(_LIBC_LIMITS_H_)
                                 ^
# 1 "<stdin>"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 349 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "<stdin>" 2
# 1 "/usr/lib/llvm-7/lib/clang/7.0.1/include/limits.h" 1 3
# 2 "<stdin>" 2

1 error generated.

and this makes GNU MPFR testing fail.
