As explained earlier, GCC 4 links the compiled code to a library
titled "libmx", which did not exist in any version of Mac OS X prior
to 10.3.9 (I think). GCC 3.3 doesn't do this.
Hmm...I am seeing different behavior, though it may be related: I get
no references to libmx in my shipped binary (just downloaded and dumped
via otool -L to be sure). What I get instead is:
dyld:
/Volumes/PdfCompress-4.4.2/PdfCompress.app/Contents/MacOS/PdfCompress
Undefined symbols:
MPWGraphRep undefined reference to _cosf expected to be defined in
/usr/lib/libSystem.B.dylib
Except of course that this symbol is present in libSystem...
