When compiling the latest fixes branch under Linux 64-bit fpc 3.0.2, with the following make command:
make all OS_TARGET=linux CPU_TARGET=x86_64 NOGDB=1 OPT=-O3 NEWOPT=-O4
The compilation failed with:
/bin/mkdir -p x86_64/units/x86_64-linux
make ./msg2inc

As a sanity check, I tried the same make command with fpc trunk (r36236) and that compiles with no errors.
