I'm planning on sending these changes to the gcc maintainers. Those who test 
gcc snapshots take a look and check if anything is wrong. I built and tested 
only with the C compiler since the C++ one is a memory hog when using gc-
page.

--------------------------------------------------------------

For a while now I've been working on gcc 2.96 to configure and build without 
having to always maintain a set of patches. This message contains part 1 
changes that should be straightforward. I posted the float_format change 
separately since I thought it might not be accepted (which it wasn't). 
Another message will have part 2 which contains changes that are more 
ambitous.

Both sets of changes were tested together and successfully bootstrapped with 
LANGUAGES="c" and with the fixproto change to handle drive letters.

gcc/Changelog:

	* x-djgpp: Delete code that conditionally modifies target_alias.
	  Delete code that conditionally modifies 'version'.
	  Delete X_CPPFLAGS.

config/Changelog:

2000-05-15 Mark Elbrecht <snowball3 AT bigfoot DOT com>

	* mh-djgpp: Conditionally set 'target_alias' to djgpp. Conditionally
	  modify 'gcc_version'.
