Thank you for fix it. :-)

You are right, I made a lot of tests and I wrong to write email. ;-)

I download from svn, compiled the package in tgz to arch and have
successfully installed.
$ svn co

I assebled my program and these are the results:

It is more correct to see the outcome of the CONFIG of __CONFIG
I do not know very clearly the issue of the mask default 18f4550.
The picp assumes this mask on file picdevrc for 18f4550:
[18F4550:defx]
cf 3f 1f 3f 83 00 00 85
c0 0f e0 0f 40 0f 00 00
00 00 00 0f 00 00 cf 3f
1f 3f 87 00 00 e5 c0 0f
But for me it should be as follows:
[18F4550:defx]
05 00 1f 1f 83 00 00 85
c0 0f e0 0f 40 0f 00 00
05 00 1f 1f 83 00 00 85
c0 0f e0 0f 40 00 00 00
I have sent an email on this subject to Jeff (privately), but got no
response yet.
