problem compiling 5.0.1

[frequens]

Hi list,

I have problems compiling 5.0.1 on two separate machines. Absolutely nothing
changed on the machines and on both the 5.0.0 version compiled with
identical configure (and still does) and worked just fine.

The first one complains:

and then dies with:

./libmapserver.a(mapfile.o):mapfile.c:(.text+0x700): more undefined
references to `msyylineno' follow
collect2: ld returned 1 exit status
make: *** [shp2img] Error 1".


The second machine does not complain at all and simply dies:

"flex --nounistd -Pmsyy -i -omaplexer.c maplexer.l
flex: unknown flag '-'.  For usage, try
        flex --help
make: *** [maplexer.c] Error 1"


Any help would be much appreciated.
