While running the test_base on CYGWIN, this message will be printed on the console: ------------------------------------------------------------------------------- DynamicLibrary::Load ------------------------------------------------------------------------------- /cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:26 ............................................................................... /cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:80: warning: Couldn't find libc.so, skipping DynamicLibrary::Load() test. /cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:84: warning: Possible candidates: /lib/libc.a /usr/lib/libc.a CYGWIN uses NEWLIB as C library and it is compiled into cygwin1.dll. This patch adds the right test case for CYGWIN, for letting the execution of the test. Closes #23781.
