# Kludge for gcc-2.6.3 bug on mips: if you use gcc global registers and -O2,
# gcc 2.6.3 gets an internal error compiling library/int.c and
# compiler/bytecode.c. As a work-around, we compile those file with -O1.
# Similarly library/bag.c needs to be compiled with -O0.
# Similarly for gcc-2.6.3 on alpha with compiler/modules.c.
# Similarly for gcc-2.7.0 on i386 with compiler/call_gen.c.
# Similarly for egcs-1.1 on sparc with library/lexer.c, library/string.c,
# and compiler/{deforest,dupelim,mercury_to_mercury,modules}.c.
# Similarly for egcs-1.1.2 on i386 with library/table_builtin.c.
