[Bug 16954] New: #defines of LONG_MAX, LONG_MIN and INT_MIN are wrong
http://bugs.winehq.org/show_bug.cgi?id=16954 Summary: #defines of LONG_MAX, LONG_MIN and INT_MIN are wrong Product: Wine Version: unspecified Platform: Other OS/Version: other Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: lkcl(a)lkcl.net a build of python2.5.2 under msys under wine goes completely tits-up due to very strange long / int interactions. the addition of a (long) typecast (around 0xNNNNL!) fixes the problem. the definitions in the standard wine / mingw32 header files are completely at odds with standard linux #defines for LONG_MAX and LONG_MIN. the definition below for INT_MIN matches the standard linux #define, and has the advantage that it actually works. +#ifdef __WINE__ /* weird: you have to typecast 0x7fffffffL to long */ +#undef LONG_MAX +#undef LONG_MIN +#define LONG_MAX ((long)0x7FFFFFFFL) +#define LONG_MIN ((long)(-LONG_MAX-1)) +#else +#ifdef __WINE__ +/* wine's #define of INT_MIN slightly faulty... + */ +#undef INT_MIN +#define INT_MIN (-INT_MAX - 1) +#endif + + -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

(Why would (long) be needed around an NNNL constant?) Can you provide a small C test program that fails to compile (or compiles wrong)?

If you are compiling with Wine's msvcrt headers then you shouldn't do that, use libc provided by your platform. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
http://bugs.winehq.org/show_bug.cgi?id=16954 --- Comment #3 from Luke Kenneth Casson Leighton <lkcl(a)lkcl.net> 2009-01-20 11:29:14 --- hi tim, sorry there's quite a bit of context missing, from other bugreports over the past few days. i'm compiling python 2.5.2 using msys running under wine. so as far as msys is concerned, there _is_ no libc: it's as if i was compiling under native win32. so ... er... actually, this bug should probably be under mingw32 not wine! ha ha :) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

A minimal test case showing the problem would be enough to reopen this bug. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
