How to compile it?
Simple "gcc glyph.c" fails with

/tmp/ccSCYXAP.o:glyph.c:(.text+0xbd): undefined reference to `__imp_CreateFontW'
/tmp/ccSCYXAP.o:glyph.c:(.text+0xbd): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `__imp_CreateFontW'

collect2: error: ld returned 1 exit status

Though I see the header files present at their appropriate places.
