Re: Problem compiling goffice under MSYS2

Thanks Morten.
Could you please elaborate a bit on this option?
Why is it necessary on win32 and not Linux?
Which consequences does it have? (I reckon, less precise calculations, 
but appart from that?)
Is it a problem if you exchange .gnumeric files with somebody who does 
not have the same option on his/her Gnumeric?

Also, goffice now compiles but there are a lot of warnings (see below 
for an example).
Is there something we can do about them?

Thanks and all the best,

Frédéric
