[flext] Building Flext on Windows... anyone got it working?

[Jamie Bullock]

HI again,

I’ve now got this building and linking on Windows. 

I’ll post some instructions at some point as I had to generate a VS config file and then rename it to config-win-pd-gcc.txt otherwise the build system (under MSYS) generates something more like a Mac config file.

Regarding the error below, I had to replace TimerVars<>::perffrq with TimerVars::perffrq and in some places perffrq with TimerVars::perffrq. I can send a pull request for this if you like? However, I think this will break builds on Windows when FLEXT_INLINE is defined. A better solution would be to either remove FLEXT_INLINE entirely or use the FLEXT_TEMPLATE macros, but I couldn’t really understand those or get them to work.

best,

Jamie
