<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">Building with MSVC seems impossible, but using <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-weight: inherit; font-family: var(--default-mono-font, "Menlo"),"DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>clang-cl</code> should IMHO be possible (due to resemblance to gcc).<br>
But I discovered the constructor / destructor in <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; font-weight: inherit; font-family: var(--default-mono-font, "Menlo"),"DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>global.c</code> did absolutely nothing due to these lines in <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; font-weight: inherit; font-family: var(--default-mono-font, "Menlo"),"DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>str.h</code>:</p>
