Irrk. The C file is very wrong indeed. Here's the relevant part where it
shoudl be declaring 'customer':
/* exec sql type customer is struct { #line 12 "array_of_struct.pgc" struct varchar_name_12 { int len; char arr[ 50 ]; } name ; #line 13 "array_of_struct.pgc" int phone ; } */ #line 14 "array_of_struct.pgc"

(all on one line, in case the MUA wraps it)

Seems like the entire definition of the struct is commented out?

Are we perhaps looking at something broken by Windows newlines?

Anyway, I've attached the full output file.

There's a chapter in the developer version of the docs. That combined
withthe README file in src/tools/msvc should get yuo there - especially if
you know a bit of Windows devving beforehand. Suggestions for improvements
are always welcome though, since not a lot of people have built something
off those instructions yet.
