That's telling, since USHRT_MAX (65535) may be the limit, then somewhere there is the use of a variable of that type (unsigned short int, uint16_t), which may be part of some specification (i.e. the format of libraries). Supporting that is: https://ghc.haskell.org/trac/ghc/ticket/5292 which mentions: "65536 symbols. This is the limit that Windows DLLs can handle (the source of the limitation is that they use 16-bit integers to represent "ordinals")" and also point to an interesting bug report (5 years old): https://sourceware.org/bugzilla/show_bug.cgi?id=12969 No answers, but at least an explanation. -- René Berber -- 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
