   4 Subject: [PATCH] compiler.m4: do not remove -g flag
   5
   6 A sed expression such as 's/-g//' not only removes the -g
   7 debugging-related flag, but also turns more specific flags such as
   8 -mfloat-gprs=double into -mfloatprs=double, which is no longer a valid
   9 flag.
  10
  11 However, it turns out that removing -g is not necessary: having -g0
  12 after -g negates the -g, and having -ggdb after -g is enough to produce
  13 debugging information for GDB.
