Hi all. New to Allegro, and C++ in general. Just some advice/comments wanted on an error I got when building allegro earlier today

here is a snip from the end of the log:

mingw32-make: *** [obj/mingw32/alleg/setup.o] Error 1

At first I thought the build failed, but I looked inside \lib\mingw32\ and alleg42.dll, allegro.def and liballeg.a were there. so i "make compress" and then "make install", I then built a sample program in code::blocks that used allegro and it worked fine.

I want to know if this is an error I should be worried about, or if indeed I should file a bug report as it suggests.

Some info about my machine and build environment:
Windows Vista 32bit
allegro 4.22
(the following are all extracted to C:\MinGW, with proper environmental variables applied)
binutils-2.17.50-20060824-1.tar.gz
dx70_mgw.zip
gdb-6.6
mingw32-make-3.81-2
mingw-runtime-3.12
mingw-utils-0.3
w32api-3.9
gcc-4.2.1-tdm-1-core-1
gcc-4.2.1-tdm-1-g++-1

I got my GCC builds from here: http://www.tdragon.net/recentgcc/
