Anyone able to build on MSYS2 Windows 11 ?

[sukerat]

Does anyone have an example of what a typical config.mk should look like when building on a MS Windows MSYS2 environment?

I get the below error when attempting to build after I have added "D_WCTYPE_T" to CFLAGS

dvtm build options:
CFLAGS = -std=c99 -I. -I/usr/include -DVERSION="0.15" -DNDEBUG -D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=700 -D_XOPEN_SOURCE_EXTENDED -D_WCTYPE_T
LDFLAGS = -lc -lutil -lncursesw
CC = cc
