The pragma switch requires an argument of auto, direct or simple, for example:

#pragma switch  /* oops -- this requires a switch mode */

maybe you meant something like:

#pragma switch simple

The pragma psect requires an argument of the form oldname = newname where old-
name is an existing psect name known to the compiler, and newname is the desired 
new name, for example:

#pragma psect  /* oops -- this requires an psect to redirect */

maybe you meant something like:

#pragma psect text=specialtext

The inline pragma expects the name of a function to follow. The function name must 
be recognized by the code generator for it to be expanded; other functions are not 
altered, for example:

#pragma inline  /* what is the function name? */

maybe you meant something like:

#pragma inline memcpy

The printf_check pragma expects the name of a function to follow. This specifies 
printf-style format string checking for the function, for example:

#pragma printf_check  /* what function is to be checked? */

Maybe you meant something like:

#pragma printf_check sprintf

Pragmas for all the standard printf-like function are already contained in <stdio.h>.

A floating-point constant must have at least one digit after the e or E., for example:

float f;

f = 1.234e;  /* oops -- what is the exponent? */

After 0x should follow at least one of the HEX digits 0-9 and A-F or a-f, for example:

a = 0xg6;  /* oops -- was that meant to be a = 0xf6 ? */

A binary digit was expected following the 0b format specifier, for example:

i = 0bf000;  /* oops -- f000 is not a base two value */

A digit in this number is out of range of the radix for the number, i.e., using the digit 8 
in an octal number, or HEX digits A-F in a decimal number. An octal number is denoted 
by the digit string commencing with a zero, while a HEX number starts with “0X” or “0x”. 
For example:

int a = 058;

/* leading 0 implies octal which has digits 0 - 7 */
