problem compiling R package processx

[Markus Hoenicka <markus.hoenicka@mhoenicka.de>]

Hi,

I've installed Cygwin on a fresh Windows 10 system yesterday. R 3.6.3.1 
runs ok, and installing some of the CRAN packages that I need also works 
ok. Trying to install the processx package (current version 3.4.2) 
throws a bunch of errors though:

$ R
[...]
> install.packages("processx")

[...and so forth...]

This makes me think that R does not properly pick up its own include 
files in /lib/R/include/ as Rinternals.h seems to define the functions 
or symbols that cause the errors above. The source file base64.c 
includes Rinternals.h, that file exists, and it is readable. Did I miss 
something?

regards,
Markus
