Cygwin uses newlib and I checked the documentation on the newlib homepage: It provides both the 'unsigned long' and the 'unsigned long long' version. Also cygwin/gcc allows to use 'unsigned long long' variables. So it's not that everything related 64 bit is not available, because I'm compiling for a 32bit Windows. Is there a special option I should use to get access to more 64 bit methods? Here is a simple test program to show the effect: #include int main(int argc, char** argv) { unsigned long long l = 0; l = std::strtoull("0x100", NULL, 16); return 0; } This is the call to the compiler: $ g++ -Wall -o tt tt.cpp tt.cpp: In function 'int main(int, char**)': tt.cpp:7:9: error: 'strtoull' is not a member of 'std' Here is my version of cygwin and gcc / g++: CYGWIN_NT-5.1 XXXXXXXX 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin g++ (GCC) 4.5.3 Mit freundlichen Grüßen / Kind regards Markus Selve zSeries I/O Firmware Developer IBM Systems &Technology Group, Systems Software Development / i390 Firmware Development ------------------------------------------------------------------------------------------------------------------------------------------- IBM Deutschland Schoenaicher Str. 220 71032 Boeblingen Phone: +49-7031-16-5143 E-Mail: mselve at de.ibm.com ------------------------------------------------------------------------------------------------------------------------------------------- IBM Deutschland Research & Development GmbH / Vorsitzender des Aufsichtsrats: Martin Jetter Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen / Registergericht: Amtsgericht Stuttgart, HRB 243294 -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
