Here's the strange part:

The currently available version of RTools 4.5 only has GCC 14.3 (and
compiles EmbedSOM without a problem).
Judging by the include paths containing /usr/lib/gcc/x86_64-pc-cygwin/,
it might be a %PATH% problem on Win-Builder, with the MSYS/Cygwin
toolchain being picked up instead of the desired UCRT one.
