[fpc-pascal] minigzip example does not compile (?)

[Juha Manninen]

I also have a gzip related issue.
I try to test with paszlib/examples/minigzip but the compiler gives :

minigzip.pas(73,40) Error: Call by var for arg no. 2 has to match
exactly: Got "LongInt" expected "SmallInt"

FPC 2.6.4 and FPC trunk seem to have identical code here.

It is possible I do something stupid. Should I add compiler flags?
