 Hello all

I want to submit following to GCC patches for branch and trunk. 
These are slightly modified from the local changes for 
building gcc-2.95.3 for mingw.  Any comments?

At the end of mingw32.h, there is this:
/* Override Cygwin's definition. This is necessary now due to the way
   Cygwin profiling code is written. Once "fixed", we can remove this. 
*/
#undef SUBTARGET_PROLOGUE

I notice that Cygwin's definition has changed.  It may now be
"fixed" for mingw, but for the nonce I am leaving the #undef in.

Danny




ChangeLog

	2001-10-09  Danny Smith  <danny_r_smith_2001 AT yahoo DOT co DOT nz>
	
	* config/i386/mingw32.h (WIN32_BUILD_RELOCATABLE_PACKAGE): New
	define.	(Thanks to Mumit Khan for suggesting macro name).
	(CPP_PREDEFINES): Define __MINGW32__ but don't set value; add
	more WIN32 defines.
	(STANDARD_INCLUDE_DIR): Remove i386- from directory name.
	(STANDARD_INCLUDE_COMPONENT): Change to MINGW.
	(MATH_LIBRARY): Undef before definition.
	(OUTPUT_QUOTED_STRING): Likewise.
