Subject: [Ada] Portability improvement for constants related to serial ports

This change improves the process that generates s-oscons.ads so that
the proper unisgned values for serial ports related constants are
generated.

Tested on x86_64-pc-linux-gnu, committed on trunk

2012-08-06  Thomas Quinot  <quinot@adacore.com>

	* s-oscons-tmplt.c, xoscons.adb: Per the Single UNIX Specification,
	types cc_t, speed_t, and tcflag_t defined in <termios.h> all are
	unsigned types. Add required special handling to have their correct
	unsigned values in s-oscons.ads.
