[SerialICE] r60 - trunk/SerialICE/util

Author: oxygene
Date: 2009-11-20 23:16:48 +0100 (Fri, 20 Nov 2009)
New Revision: 60

Modified:
   trunk/SerialICE/util/romcc.c
Log:
Replace open/read/close with fopen/fread/fclose in romcc.
The filesize is now determined using fseek/ftell, like in cbfstool.

Thank you Stefan, for the hint.

Tested on mingw
