Geoff Keating f2682362a5 In gcc/: 
* fixinc/gnu-regex.c: Change 'CYGNUS LOCAL' to 'EGCS LOCAL'.

In gcc/ch/:
	* Make-lang.in: Remove 'CYGNUS LOCAL' markers.
	* Makefile.in: Likewise.
	* configure: Likewise.

# --build=TARGET specifies configuration of machine you are

# --prefix=DIR specifies directory to install in.
# --local-prefix=DIR specifies directory to put local ./include in.
