Bug ID: 101388
Summary: Unconditional use of __MAX_BAUD
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: gaiusmod2 at gmail dot com
Target Milestone: ---
Target: *-*-solaris2.11
Building the devel/modula-2 branch on Solaris 11 fails with undefined
references
to __MAX_BAUD in two places:
/vol/gcc/src/git/modula-2/gcc/m2/mc-boot-ch/Gtermios.c: In function
'termios_GetFlag':
/vol/gcc/src/git/modula-2/gcc/m2/mc-boot-ch/Gtermios.c:872:27: error:
'__MAX_BAUD' undeclared (first use in this function)
*b = ((t->c_cflag & __MAX_BAUD) == __MAX_BAUD);
^~~~~~~~~~
/vol/gcc/src/git/modula-2/gcc/m2/gm2-libs-ch/termios.c: In function
'termios_GetFlag':
/vol/gcc/src/git/modula-2/gcc/m2/gm2-libs-ch/termios.c:877:27: error:
'__MAX_BAUD' undeclared (first use in this function)
877 | *b = ((t->c_cflag & __MAX_BAUD) == __MAX_BAUD);
| ^~~~~~~~~~
__MAX_BAUD seems to be Linux/glibc specific, but the current problem is
obviously
cause by a wrong guard which checks for defined(MAX) instead of
defined(__MAX_BAUD).
Correcting this lets the build continue.
