Suffixes for fixed-point constants are broken as well. GCC allows the letters
in them to be in any order, except that "ll" must be together and in the same
case. GCC does not reject 'l' by itself as invalid. N1169, a draft of TR
18037, says that a suffix is case-insensitive but isn't clear about whether
that means that a suffix can mix cases within a suffix or just that
all-uppercase or all-lowercase varieties are valid.
Function interpret_float_suffix in libcpp/expr.c was originally quite simple.
It was not designed to support long suffixes like those for decimal-float and
fixed-point constants. It will need to get even more complicated with support
for suffix 'd' for double contants (PR c/39027) and pragma
FLOAT_CONST_DECIMAL64 (PR c/39037), which specifies whether an unsuffixed float
constant is double or _Decimal64. I'm looking at reasonable ways to rewrite
it.
