* Address miscellaneous compiler warnings This commit looks through all compiler warnings generated by clang and MSVC (including Windows ARM64) and picks the low hanging fruit. Compiling (clang version 20.1.8) with added flags: -Wno-incompatible-pointer-types -Wno-pointer-sign -Wno-unused-but-set-variable -Wno-unused-local-typedef Changes: bootstrap.c: warning : format specifies type 'unsigned int' but the argument has type 'DWORD' (aka 'unsigned long') ctc: warning : unused variable 'saw_if' dyn76.c: warning : variable 'R4' is used uninitialized whenever 'if' condition is false getopt.c: warning : a function definition without a prototype is deprecated in all versions of C and is not supported in C23 hdl.c: warning : unused parameter 'flag' [-Wunused-parameter] msgenu.h: ... an invalid preprocessing token [-Winvalid-token-paste] tt32api.h: warning : non-portable path to file 'tt32if.h'; specified path differs in case from file name on disk vstore.h: warning : absolute value function 'labs' given an argument of type '__ptrdiff_t' (aka 'long long') but has parameter of type 'long' which may cause truncation of value zvector2.c: remove '_USE_128_' define that was moved to zvector.h --- Compiling (cl.exe version 19.50.35725) with added flags: /W4 /wd4323 /wd4152 /wd4703 /wd4201 Changes: warning C4245: 'function': conversion from 'int' to 'BYTE', signed/unsigned mismatch (compiling source file control.c) warning C4389: '!=': signed/unsigned mismatch (compiling source file control.c) warning C4100: 'secs': unreferenced parameter (compiling source file netsupp.c) warning C4100: 'iFlags': unreferenced parameter (compiling source file tuntap.c) --- Compiling (gcc (Ubuntu 15.2.0-4ubuntu4) 15.2.0): Compiling (gcc (GCC) 16.0.1 20260305 (Red Hat 16.0.1-0)): Wunterminated-string-initialization was introduced in GCC-15. An alternate solution would be to use: __attribute__((nonstring)) Changes: loadmem.c:102:32: warning: initializer-string for array of ‘char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (9 chars into 8 available) [-Wunterminated-string-initialization] --- Compiling (clang version 22.1.1 (Fedora 22.1.1-2.fc44)) Compiling (gcc (GCC) 16.0.1 20260305 (Red Hat 16.0.1-0)) Changes: cgibin.c:1662:1: warning: ‘/*’ within comment [-Wcomment] dasdcat.c:463:13: warning: variable ‘trks’ set but not used [-Wunused-but-set-variable=] dasdpdsu.c:172:13: warning: variable ‘trks’ set but not used [-Wunused-but-set-variable=] hscutl.c:1325:15: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] hscutl.c:1326:15: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] msgenu.h:222:33: warning: ‘off_size’ may be used uninitialized [-Wmaybe-uninitialized] (after fixing above) transact.c:230:13: warning: variable ‘effective_addr2’ set but not used [-Wunused-but-set-variable=] transact.c:708:9: warning: variable ‘effective_addr1’ set but not used [-Wunused-but-set-variable=] * VS2013: fix compile error C99 Compliant floating-point classification macros were introduced in VS2013; see: https://devblogs.microsoft.com/cppblog/c99-library-support-in-visual-studio-2013/ * w32stape.c: CAS multi-threaded initialization Use Compare-and-Swap in initialization functions that may be called from multiple threads. * opcode.h: avoid declaring ops w/ dynamic instructions Allows modification of the storage class specifier and attributes of undefined instructions (UNDEF_INST).
