[Bug c/40016] regex_internal.h:185: error: integer overflow in preprocessor expression

[jakub at gcc dot gnu dot org]

------- Comment #3 from jakub at gcc dot gnu dot org  2009-05-04 14:52 -------
Not surprisingly when the error is during preprocessing.
regex.h parted ships (why?) is broken by the #elif changes, there is:
#if some_condition_that_is_true_on_sane_targets
...
#elif BITSET_WORD_MAX == (0xffffffff + 2) * 0xffffffff
/* Work around a bug in 64-bit PGC (before version 6.1-2), where the 
   preprocessor mishandles large unsigned values as if they were signed.  */
...
#endif

To make GCC happy about this at least the #elif should be changed into #else
#if ... #endif.
