There were some problems when I defined DIR_SEPARATOR in gcc configuration
as many programs expect to get '/' in dependencies (for example RHIDE).
Therefore I removed this definition in final version. I didn't notice problems,
so I released it. 

The current problem is that modified version of mktemp() I used fails when TMPDIR 
ends with backslash. 

For   TMPDIR=D:/    choose_temp_base() removes trailing slash so all works Ok
For   TMPDIR=D:\    choose_temp_base() does not do this so we have the problem    
     
Unfortunatelly looks that the only correct way is to define DIR_SEPARATOR
in config/xm-go32.h. I hoped to avoid this.

There is more problems: 
  'gcc -M -c foo/bar.c'  outputs  'bar.o:  foo/bar.c  ...'
  'gcc -M -c foo\bar.c'  outputs  'foo\bar.o:  foo\bar.c  ...'

There is still one question whether there is possible to get backslashes 
converted to normal slashes when outputing dependencies (for modified 
version of mktemp there is no problem to do this) to have for example
c:/djgpp/include/stdio.h in dependencies instead of c:\djgpp\include\stdio.h

Otherwise these would be urgent need for patched version of RHIDE and
perhaps something else

Yes it looks for TMP and TEMP if previous ones is not found.
