Proposed patch
When trying to build the current devel/modula-2 branch on Mac OS X 10.7, it
failed to compile mc-boot-ch/Gtermios.cc, pge-boot/Gtermios.cc, and
gm2-libs-ch/termios.c:
/vol/gcc/src/hg/master/modula-2/gcc/m2/mc-boot-ch/Gtermios.cc: In function 'int
termios_SetFlag(termios*, Flag, int)':
/vol/gcc/src/hg/master/modula-2/gcc/m2/mc-boot-ch/Gtermios.cc:1091:26: error:
cannot convert 'tcflag_t*' {aka 'long unsigned int*'} to 'unsigned int*'
1091 | return doSetUnset (&t->c_iflag, IGNBRK, b);
| ^~~~~~~~~~~
| |
| tcflag_t* {aka long unsigned int*}
/vol/gcc/src/hg/master/modula-2/gcc/m2/mc-boot-ch/Gtermios.cc:168:27: note:
initializing argument 1 of 'int doSetUnset(unsigned int*, unsigned int, int)'
168 | doSetUnset (unsigned int *bitset, unsigned int mask, int value)
|
and many more instances of the same.
As the error says, tcflag_t is unsigned long on that Darwin version.
The fix is easy: just don't make doSetUnset assume the type of tcflag_t, but
use the correct type directly. This is what the attached patch does, which
allows the build to continue.
