'read', the trap handler executes and 'read' returns an exit status

60. The 'printf' builting uses 'double' (via 'strtod') to convert
arguments corresponding to floating point conversion specifiers,
instead of 'long double' if it's available. The 'L' length
modifier forces 'printf' to use 'long double' if it's available.
