Hi, I've built gpc-20070904 for openSuSE 12.1 and the gpc command fails unless I type the full path name of gpc on the command line.
For example, if I type gpc -- verbose hello.pas , gpc calls the assembler in 32 bit mode. Like this ...

On the other hand, when I call gpc using its full path name, everything works as expected ...

With a full pathname, gpc prints some version info and exits (as expected)

Also,

Also, calling gpc (ie in short form, not using full pathname) from a shell script works as expected, so the test scripts work. Results copied below. I built gpc on openSuSE 11.3using the same build process (as far as I know) and there were no problems.
OK, it's not a catastrophic failure, but I would like to fix it. Does anyone know what causes this, and what I need to do about it? Any ideas much appreciated.
