What is that .w file?

[silvio]

while compiling yafu2 in MSVC, I have an insurmoumtable problem with siever-config.w of lasieve5_64 project.
MSVC attempt compiling as it were a .c file! and reports more than 700 errors. Could anyone shed a light?
TIA

.w files are legacy files - the author of the sieve wrote his code in CWEB (Don Knuth's) language. This language allows to write and document the code simultaneously. It is quite rarely used these days.

You can use ctangle to extract C code (and then compile it), and optionally cweave to get the documentation out.
