Building gcc-2.7.2.3 for winnt

["Smith, Eric" <erics at eastman dot com>]

To all,

I am currently trying to build the integrated version of gcc and gnat as
defined in the gnat readme files.  I hav gotten to the point of actually
building the compiler and am running into the most annoying errors I can
think of.

------------------------------------------------------------------------
---------------------------------
If I configure the system using 
	bash-2.01$ configure i386-*-winnt3
and build the compiler I get the following: (edited to eliminate long
path names)

bash-2.01$ make CC=gcc CFLAGS="-O2" LANGUAGES="c ada"
gcc  -DIN_GCC   -O2     -I. -I. -I./config \
       -DGCC_INCLUDE_DIR=\"/usr/local/lib/gcc-lib/i386-*-winnt3/2.7.2.3/
include\" \
       -DGPLUSPLUS_INCLUDE_DIR=\"/usr/local/lib/g++-include\" \
       -DLOCAL_INCLUDE_DIR=\"/usr/local/include\" \
       -DCROSS_INCLUDE_DIR=\"/usr/local/lib/gcc-lib/i386-*-winnt3/2.7.2.
3/sys-include\" \
       -DTOOL_INCLUDE_DIR=\"/usr/local/i386-*-winnt3/include\" \
       -c `echo ./cccp.c | sed 's,^\./,,'`

bash-2.01$

The major error is the syntax error in string.h (Line 56).

Here is the problem section of string.h

_PTR 	 _EXFUN(memchr,(const _PTR, int, size_t));
int 	 _EXFUN(memcmp,(const _PTR, const _PTR, size_t));
_PTR	 _EXFUN(memcpy,(_PTR, const _PTR, size_t));
_PTR	 _EXFUN(memmove,(_PTR, const _PTR, size_t));
_PTR	 _EXFUN(memset,(_PTR, int, size_t));
char 	*_EXFUN(strcat,(char *, const char *));
char 	*_EXFUN(strchr,(const char *, int));
int	 _EXFUN(strcmp,(const char *, const char *));


As you can see, there is no `0' in string.h

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

If I instead try to configure from the command line using 
	C:\Unix\src\gcc>configure winnt i386

The results are :

This section of Makefile is as follows (starting at line 106)

Can anyone give me assistance on getting these things built?
