'-print-prog-name' does not work on Vista OS

'-print-prog-name' does not work on Vista OS

[Siddharth Sengupta]

Hi,

We have built a MinGW H8 toolchain using gcc-4.2-20080402,
binutils-2.18.50 and 
newlib-1.16.0. 

The following command did not give the expected output on Vista OS for 
this toolchain,
Command: h8300-elf-gcc -print-prog-name=cc1
Output: cc1
Expected Result:
$(TCINSTALL)/h8300-elf/bin/../libexec/gcc/h8300-elf/4.2-
		GNUH8_v0802/cc1.exe
where, $(TCINSTALL) is the toolchain installation directory.

The same command when run on WinXP, gave the correct path,
Command: h8300-elf-gcc -print-prog-name=cc1
Output:
$(TCINSTALL)/h8300-elf/bin/../libexec/gcc/h8300-elf/4.2-GNUH8_v0802/
	cc1.exe
Expected Result: Same as Output
where, $(TCINSTALL) is the toolchain installation directory.

Additional Information:

The sources used for building the GNU H8 MinGW toolchain are 
gcc-core-3.4.5-20060117-3.tar.gz,
gcc-g++-3.4.5-20060117-3.tar.gz, binutils-2.17.50-20060824-1.tar.gz, 
mingw-runtime-3.12.tar.gz and w32api-3.9.tar.gz.

We also downloaded "MinGW-5.1.4.exe" from the official MinGW website and
found
that the command works as expected on Vista OS.
This used the following versions: 
gcc-core-3.4.5-20060117-3.tar.gz,
gcc-g++-3.4.5-20060117-3.tar.gz, binutils-2.17.50-20060824-1.tar.gz,
mingw-runtime-3.14.tar.gz and w32api-3.11.tar.gz. 

Command: gcc -print-prog-name=cc1
Output: C:/MinGW/bin/../libexec/gcc/mingw32/3.4.5/cc1.exe
Expected Result: Same as Output 

To confirm whether the difference in MinGW versions resulted in this
behaviour,
we built MinGW GNU H8 toolchain using the above versions. 
However, the '-print-prog-name' command still gave the same problem.
The same command when run on WinXP, worked correctly.

Can somebody please tell where the problem exactly lies?

This is PR33281 (which was not a complete fix) and PR35916 (which
concerned the remaining instances in libiberty not covered by the
previous) which was finally fixed for 4.4.0.  The fix should be trivial
to backport to older versions.  Alternatively you can override CFLAGS
and BOOT_CFLAGS manually on the make command.

We referred to PR33281 and PR35916 as mentioned and built the toolchain
again after overriding the CFLAGS in the '*config/mh-mingw' file.
BOOT_CFLAGS was already overridden by a patch applied earlier in the
same file. 
However this fix doesn't seem to work as the problem still persists on
the Vista machine. The 'h8300-elf-gcc -print-prog-name=cc1' works on the
Windows XP machine as before.

Is there any thing else that needs to be done?

Thanks and Regards,

Since PR33281 and PR35916 were fixed in GCC 4.4.0, we downloaded the
GCC-4.4-20080822 sources, and built a MinGW H8 toolchain using the
following sources:
1) Binutils-2.18.50  
2) Newlib-1.16.0 and 
3) GCC-4.4-20080822
Additional Information: MinGW versions used are same as mentioned
before i.e. mingw-runtime-3.12.tar.gz and w32api-3.9.tar.gz.

But even with this toolchain the problem still persists i.e. the 
command "-print-prog-name=cc1" only echoes back "cc1". However the
same problem is now seen not only in Vista but in Windows XP too.
Could you please suggest where exactly we are going wrong?
