+
+ Avoid unwanted GCC warning diagnostic messages.
+
+ * Makefile.in (libm_dummy.c): Remove "static" qualifier from...
+ (__mingw_libm_dummy): ...this variable; it caused "-Wunused-variable"
+ warning diagnostics, when compiled with "-Wall".
+
+ * main.c (WinMain): Remove unnecessary argument names from prototype.
+ (main): Make its argument list conform to convention, otherwise it
+ causes a "-Wmain" warning diagnostic when compiled with "-Wall".
+
+ * mingwex/clocktime.c (clock_gettime) [clock_id-type]
+ * mingwex/clockapi.c (clock_api_getres_interval) [clock_api->type]:
+ Ensure that switches include default cases; this avoids a "-Wswitch"
+ warning diagnostic message, in each case, when compiled with "-Wall".
+
+ * mingwex/cryptnam.c (crypto_random_filename_char): Remove "unsigned"
+ qualifier from both argument and return type; this avoids an argument
+ type mismatch, raising a "-Wpointer-sign" warning when called from...
+ (__mingw_crypto_tmpname): ...here, and compiled with "-Wall".
+
+ * mingwex/imaxdiv.c: Tidy layout; assert copyright.
+ (lldiv): Correct return type; explicitly disable "-Wattribute-alias"
+ diagnostic messages, under GCC pragma control.
+
+ * mingwex/ofmt.c [__crtofmt__] (__mingw_set_output_format_fallback)
+ [__crtnfmt__] (__mingw_get_printf_count_output_fallback): Likewise,
+ disable "-Wattribute-alias" diagnostics.
+
+ * mingwrt/mingwex/stdio/pformat.c (__pformat_ignore_flags): Adjust
+ layout, to avoid a "-Wmisleading-indentation" warning diagnostic.
+ (__pformat_argmap) [length]: Add a no-op default case, to avoid a
+ "-Wswitch" warning diagnostic message.
+
+ * mingwrt/profile/mcount.c: Explicitly disable "-Wframe-address"
+ diagnostics, under GCC pragma control, to avoid warnings relating...
+ (__builtin_return_address): ...this, when called from...
+ (mcount): ...here.
+
+ * mingwrt/setargv.c (__mingw_setargv): Insert parentheses, as advised,
+ to eliminate "-Wparentheses" diagnostic messages.
