Compiling the following simple snippet:
void foo(void)
{
int i = 0x4E+0x23;
}
triggers the error message indicated in the summary.
Analysis of the problem shows that the macro VALID_SIGN() used inside
lex_number() (libcpp/lex.c) misidentifiex the plus sign following the
E (possible exponent) character as still being part of the number, even
though this is impossible since the number started with 0x, so the
exponent is required to be introduced with `p' or `P'.
IMHO, the number parser needs to detect the possible 0x prefix early,
and pass this information down to VALID_SIGN() so this macro can
definately decide whether either of `p' or `e' is the valid exponent
character within the current context.

------- Comment #1 from schwab at suse dot de 2007-09-24 21:13 -------
0x4E+0x23 is a single preprocessing number. If that cannot be turned into a
valid token then the program is malformed. Put in some space.
