My intention would be that the examples are able to be compiled with 
MSVC. The -std=c89 option was added with the intention that warnings 
would be visible to GCC users upon use of non-c89 features.

I've realised that doing this properly requires more than this. On 
it's own, -std=c89 doesn't make much of a difference, catching not 
much more than // comments. To generate warnings about non-c89 
features with GCC requires -pedantic - and then several options to 
disable warnings for features that MSVC does support e.g. 
-Wno-long-long, -Wno-variadic-macros, -Wno-overlength-strings)

I plan to submit patches that more fully address this in the next 
few days.

Thanks - nice to know.
