This has likely been broken (for me) for a bit, but I only checked the logs from my build script today, after trying to build on a new WIn10 laptop...
FWIW, the 64-bit build is fine, which possibly explains why I never noticed there was an issue: The build machine runs a different gcc variant for the 32-bit and 64-bit targets, for obscure historical reasons...
The 32-bit version reports itself as: gcc version 6.3.0 (MinGW.org GCC-6.3.0-1)
The 64-bit version is: gcc version 5.1.0 (tdm64-1)
Anyway, here's the error:

make[1]: *** [fluid.o] Error 1
The crux is this code, added to fluid.cxx in 1.4:
// returns fileno(FILE*):
// (file must be open, i.e. _fpt must be non-null)
// *FIXME* we should find a better solution for the 'fileno' issue
int fileno() const {
#ifdef _MSC_VER
return _fileno(_fpt); // suppress MSVC warning
#else
return ::fileno(_fpt);
#endif
} // non null if file is open
Which chokes on my 32-bit build because the "stdio.h" in that system defines:
#define _fileno(__F) ((__F)->_file)
#ifndef _NO_OLDNAMES
#define fileno(__F) ((__F)->_file) <-- this is the problem in my build!
#endif
And that #define then chokes the fluid.cxx code, preventing it from compiling...
