Description Hin-Tak Leung 2009-09-24 23:40:23 UTC
svn-r152128 failed make bootstrap4-lean quite early with: (don't worry about the r150353 part below - I had to ftp a diff from one machine to the machine which does the building, so I only transport a diff from an earlier checkout).

-----------------------------

it is a generated file, and it doesn't seem to like the two typedef int64_t lines:

---------------------------
/* Define intmax based on what we found */
#ifdef _INT64_T  
typedef int64_t       intmax_t;
#else 
typedef long          intmax_t;
#endif           
#ifdef _UINT64_T
typedef uint64_t      uintmax_t;
#else                                              
typedef unsigned long uintmax_t;
#endif          
-------------------------
Comment 1 Hin-Tak Leung 2009-09-24 23:51:44 UTC
int64_t and uint64_t are both already defined in /usr/include/inttypes.h - 
it appears that intmax_t and uintmax_t may also be defined elsewhere as well, although I couldn't locate it.

(In reply to comment #1)
> int64_t and uint64_t are both already defined in /usr/include/inttypes.h -

I thought I should explain the 2nd sentence a bit - I tried cleaning the relevant bit out and leaving just these two:
 
typedef long          intmax_t;
typedef unsigned long uintmax_t;

and compilation failed with a message about 'long long long' and 'unsigned long long long'. So it appears that intmax_t was expanded to 'long long' along the way.

Already fixed for 4.5.0.
