[ECOS] Re: Can not compile API file

[m mariga]

Hello everyone,
I am very very sorry to inform you that my last reported error was not 
concerned with installing USB driver.
As I ported eCos to my sh7705 target,I proceeded to includ functions step by 
step.
First I included TCP/IP package,then implemented USB driver.
My only-TCP/IP-implemented version caused the same error so I knew I have 
not correctly implemented TCP/IP package.
But I do not know why those errors occure.
I re-append making errors below.Please teach me what caused these errors.

I relate what I have done.
I previously succeeded to port eCos2.0(CVS current) on SH7709 board with 
TCP/IP package.
I copied this package source into my new target package.And I developed new 
target on eCos 3.0.

All errosr are related to macros(like INT_MAX).
For example support.c's 620 line is next.
        if (ticks > INT_MAX)

Are these errors relateted to the difference between eCos 2.0 and eCos 3.0 ?
Would you please help me out of predicament ?
