problem finding limits.h when building a python extension

[mjtrac]

I'm trying to build a python extension, psycopg2, on tiny core, and I run into a problem where gcc says it cannot find a file, limits.h, that ls says exists on the system. 

There is some sort of issue between syslimits.h and limits.h involving recursive calls, but I've never had this problem on regular linux.  Anyone have any suggestions?  Thanks in advance.

(Output from gcc is attached.)

Not sure about it, but as soon as I hit such a problem I run (without much thinking and even properly reading the error message):
    tce-load -wi linux-headers-KERNEL

Thanks.  Unfortunately, that tells me that linux-headers-3.0.3-tinycore is already installed.

It sounds like you don't have the full compiletc set installed. limits.h should be in /usr/include.
