When building GDB with clang 16, I got this,
CXX maint.o
maint.c:1045:23: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
m_space_enabled = 1;
^ ~
maint.c:1057:22: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
m_time_enabled = 1;
^ ~
maint.c:1073:24: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
m_symtab_enabled = 1;
^ ~
3 errors generated.
Work around this by using bool bitfields instead.
Tested by rebuilding on x86_64-linux with clang 16 and gcc 12.
