[fpc-devel] strange error "checksum changed" in package, when compiling project.

[Martin]

Just checking, if there may be a simple fault on my side, or if I 
stumbled on a bug (fpc 2.6.2 and trunk (from a few weeks ago))

It happens with circular unit references via uses in implementation. (I 
know "not advisable design", but a valid language feature)

The circle is in a package, the package compiles fine.

When I compile a project, using the package (therefore only path to ppu 
files)

Hint: Start of reading config file 
C:\FPC\rel_2_6_2\gw\bin\i386-win32\fpc.cfg
Hint: End of reading config file C:\FPC\rel_2_6_2\gw\bin\i386-win32\fpc.cfg
