As no one protested, accepted or even commented, I pushed a patch. Hope its Ok
See: https://repo.or.cz/tinycc.git/commitdiff/40f01478d82a3dc225c3299062741fc36cb e2b56 Now, whether it is compiled with m32 or -m64 on Windows, this sample gives the same expected result: c:\tmp>tcc -m32 foo.c -o foo.exe && foo 100000000 8 1 8 c:\tmp>tcc -m64 foo.c -o foo.exe && foo 100000000 8 1 8 c:\tmp>more foo.c #include <stdio.h> #include <stdlib.h> #include <math.h> int main() { long long x = strtoll("0x100000000", NULL, 0); printf("%llx %d\n", x, (int)sizeof(x)); x = (x >> 32); printf("%llx %d\n", x, (int)sizeof(x)); } Last but not least, it lets GNUmake compile ROOTB on Windows with this version of tcc.

As _strto[u]ll exists in msvcrt.dll and works well for either m32|-m64 tcc.h can just test for _WIN32.
