mmm, I figure out that's because the number of args to call this routine integer_types() should be the same as the number of
@types's elements (i.e. 6) which is not allways the case:
e.g.
252 } elsif ($spec eq 'i86') {
253 return (' -Di386=1 -D__i386=1 -D__i386__=1' .
254 &integer_types (8, 16, 32, $m64 ? 64 : 32, 64) .
255 &float_types (1, 1, 21, [24,8], [53,11], [64,15]) .
256 &define_size_t ($m64 ? "long unsigned int" : "unsigned int"));
257 } elsif ($spec eq 'sparc') {
258 return (' -Dsparc=1 -D__sparc=1 -D__sparc__=1' .
259 &integer_types (8, 16, 32, $m64 ? 64 : 32, 64) .
260 &float_types (1, 1, 33, [24,8], [53,11], [113,15]) .
261 &define_size_t ($m64 ? "long unsigned int" : "unsigned int"));
262 } elsif ($spec eq 'sparc64') {
263 return (' -Dsparc=1 -D__sparc=1 -D__sparc__=1 -D__sparcv9__=1 -D__sparc64__=1 -D__arch64__=1 -D__LP64__=1' .
264 &integer_types (8, 16, 32, 64, 64, 128) .
265 &float_types (1, 1, 33, [24,8], [53,11], [113,15]) .
so one possible fix could be:
--- /usr/bin/cgcc.orig 2009-11-28 17:41:28.000000000 +0000
+++ /usr/bin/cgcc 2009-12-06 11:55:32.000000000 +0000
@@ -133,7 +133,7 @@
my @types = (['SCHAR',''], ['SHRT',''], ['INT',''], ['LONG','L'], ['LONG_LONG','LL'], ['LONG_LONG_LONG','LLL']);
