[bug-gawk] [PATCH] Windows compilation error: #define concatenation in 'io.c'

[Jannick]

Hi,

 

My first post to this list, hope that everything is OK with it.

 

A tiny patch for your consideration avoiding a compilation error on Windows (concatenation in #define statement). The proposed solution might not be the most elegant way, but it works here.

 

Thanks,

J.
