Re: Fw: GCC - 64bit long long type, support in lib

The gcc supports 64bit int it seems, but the library as downloaded does not,
for example try

 long long ldec = 0x11000000000LL;
 printf("%s: 0x%Lx,%Ld; %s\n","test",ldec,ldec,"test2");

I think its a problem with configure, I see in configure where test code is
generated for  #define HAVE_LONG_LONG 1
but what configure file is supposed to get then set with this
flag....?config.h ? hmm not happening.

~$ cat bar.c int main() { long long foo = 0x1100000000000022LL; printf("foo = %lld (0x%016llx)\n",foo,foo); } ~$ gcc -o bar bar.c ~$ ./bar foo = 1224979098644774946 (0x1100000000000022) ~$ cat > bar.out

WFM, when I use the *correct* modifier. 'L' applies to floating-point; you want 'll'. Alas, this doesn't seem to be listed in 'man 3 printf'; looks like that should be fixed.

(Yes, I know, http://cygwin.com/acronyms/#SHTDI... maybe I will, later. Alternatively, can we use the Linux manpage?)
