Hi there,
I am trying to build libserialport on a Windows 10 machine with MSYS2.
The ./autogen.sh and ./configure steps complete without errors.
When issuing the make command I get the following errors:
make all-am
CC serialport.lo

if ((timeout_overflow = timercmp(&delta, &max_delta, >)))
^
make[1]: *** [Makefile:527: serialport.lo] Error 1
make: *** [Makefile:398: all] Error 2
How can I fix those errors?
