two points.  the 'strlen()' function returns a 'size_t', that is, an unsigned
value, while both 'int' and 'ssize_t' hold signed values; however, if that was
the problem you would have seen "warning: conversion to..." messages, not
errors.

second, I just downloaded 'Hg.226.Bigarade' and built it; one single warning
message aside, the program builds cleanly (on a Slackware GNU/Linux box).  so,
sorry, cannot help any further, but my advice is: either create a virtual
machine running a Linux, or install 'cygwin'[*], or explore whether the Windows
10/Ubuntu thing works for you.

(I read the following quote in someone's signature block years back
(paraphrased): "computers are like air-conditioning, they stop working when you
open Windows."  ;-))

[*] there are other s/wares too, like 'MinGW'.


regards, jr.
