I have built GPC 20041218 on GCC 3.3.4 on AIX 5.2 on an IBM p650 machine with multiple powerpc cpus.

I have also installed the 64 bit library for GPC.

http://www.gnu-pascal.de/crystal/gpc/en/mail11263.html

Using standard 32 bit compilation, I receive copious warnings along the lines of

/home/pkeenan/local/bin/../lib/gcc-lib/powerpc-ibm- aix5.2.0.0/3.3.4/../../../../powerpc-ibm-aix5.2.0.0/bin/ld: warning: powerpc:601 architecture of input file `/home/pkeenan/newgcc/lib/gcc- lib/powerpc-ibm-aix5.2.0.0/3.3.4/libgpc.a(files.o)' is incompatible with rs6000:6000 output

and many more like this

however the program compiles and gives

SizeOf( LongReal) = 8

sin( 1.2345) = 0.943983323944511099057308456395

sin( 1.2345) = 0.943983323944511099057308456395 = 0.943983323944511099057308456395

sin( 1.2345) = 0.943983323944511099057308456395 = 0.943983323944511099057308456395 = 0.943983323944511099057308456395

64 bit compilation -maix64 gives the same answer

SizeOf( LongReal) = 8

sin( 1.2345) = 0.943983323944511099057308456395

sin( 1.2345) = 0.943983323944511099057308456395 = 0.943983323944511099057308456395

sin( 1.2345) = 0.943983323944511099057308456395 = 0.943983323944511099057308456395 = 0.943983323944511099057308456395

For the C version GCC gives

GCC with -maix64 gives the error without the warnings

/tmp//ccuhHGVI.o(.pr+0x1c):longreal.c: undefined reference to `.sin'

collect2: ld returned 1 exit status

the native AIX cc compiler gives
