This files should never be built on Windows in the first place.
Can you post the full output of the "./configure" and "make"
command and attach them as text files?<br>
</p>
<p>Just for the record, can you successfully build other software
with Msys2? Just to rule out a general problem with your Msys2
installation.</p>

interestingly, that build also generates a warning message
while compiling s_inter.c (which defines sys_setalarm()
under the right set of compiler flags) indicating that
_WIN32 is not defined.<br>
<br>
s_inter.c: In function ‘sys_init_deken’:<br>
s_inter.c:998:4: warning: #warning unknown OS [-Wcpp]<br>
998 | # warning unknown OS<br>
<br>
So if I instead build with CFLAGS=-D_WIN32, I get a
different set of errors while building s_inter.c<br>
<br>
/usr/include/w32api/psdk_inc/_fd_types.h:100:2: warning:

Could someone please enlighten me? Or point me to relevant
