Hey guys,

I'm writing an snmp plugin for m0n0, and php takes way too long to
execute.  So, I took my simple script and converted it to C to make my
very first ever C program (scary!).

I run Gentoo on my laptop, and GCC compiles it fine there (version
3.3.5).  However, when I transfer the file to my FreeBSD 4.11 box,
running 2.95 gcc, it bombs out with a syntax error before '*' where I
have the 'FILE *in;' declaration.

Does anyone with more C foo than me have any ideas on how to fix my
problem?

Please keep in mind this is my first C program ever....

Justin
