math: Work around bug in Solaris 9 implementation of ldexp.
The bug is that ldexp(-1, -1075) should return -0, but the
Solaris 9 implementation returns +0.
From-SVN: r186913
This option, which is enabled by default, causes the preprocessor to warn
when a string or character literal is followed by a ud-suffix which does
not begin with an underscore. According to [lex.ext]p10, this is
ill-formed.
Also modifies the preprocessor to treat such ill-formed suffixes as separate
preprocessing tokens. This is consistent with the Clang front end (see
http://llvm.org/viewvc/llvm-project?view=rev&revision=152287), and enables
backwards compatibility with code that uses formatting macros from
<inttypes.h>, as in the following code block:
int main() {
int64_t i64 = 123;
printf("My int64: %"PRId64"\n", i64);
}
