This is not meant to be a bug report,
but just a brief account of compiling gcc-2.5.2
on a Mips Magnum running Riscos5,
using "configure --target=mips-mips-riscos5bsd"

I met 2 minor problems:

(1) Permissions.
A number of the shell-scripts did not have +x permission.
Also the files cp-parse.[ch] did not have +w permission,
which was required since they were run through sed.

This was probably my fault, or perhaps an artifact
of gzcat | tar xvf - ?

(2) _tolower in collect2
collect2 reported that the function _tolower was not found.
This appears to be an bug in mips ldopen(),
eg the problem arises with the following program,
but goes away if the commented-out lines are included.

================================================

#include <stdio.h>
#include <filehdr.h>
#include <syms.h>
#include <ldfcn.h>
#include <ctype.h>
/*
#undef _tolower
*/

main()
{
	LDFILE *ldptr;

               if ( ldopen("collect.o", ldptr) != NULL )

               {
                    /* check magic number */
                    /* process the file */
               }
} 

/*
int _tolower(int c)
{
	return tolower(c);
}
*/

================================================

I solved the problem by adding a file mytolower.c , as above

================= mytolower.c ==================

#include <ctype.h>
#undef _tolower

int _tolower(int c)
{
	return tolower(c);
}

================================================

The corresponding line in Makefile was changed to

================================================

	$(CC) $(ALL_CFLAGS) $(LDFLAGS) -o collect2 \
	collect2.o version.o mytolower.o $(LIBS)

================================================

(3) glib++-2.5.1
There seems to be an error in the file libio/iopopen.c

================================================

int
_IO_proc_close(fp)
     _IO_FILE *fp;
{
...
  if (status < 0)
    return status;
{ /* This line added by tim@maths.tcd.ie */
#if defined(SIG_BLOCK) && defined(SIG_SETMASK)
...
#else
#ifdef USE_SIGMASK
...
#else
  typedef void (*void_func)(int);
  void_func intsave = (void_func)signal(SIGINT, SIG_IGN);
...
#endif
} /* This line added by tim@maths.tcd.ie */
}

================================================

It seems that this file was written for compilation with g++,
but is actually compiled with gcc .

I'd be interested to know if others have met the same problems 
in compiling gcc-2.5.2 on Mips.

I should say that gcc-2.5.2 appears to run perfectly.
The include file problems that arose with earlier versions
(eg the conflicting types given to size_t)
seem to have been resolved.
