As a supplement to the -- by necessity -- terse error messages generated by
gcc, it would be fantastic (IMHO) if a new option could be added to gcc to
display the current language standard along with the _section_ in that standard
that the error applies to.
IE, rather than...
hello.c:1:10: error: #include expects "FILENAME" or <FILENAME>
We could have:
hello.c:1:10:c99:1.2.3.4: error: #include expects "FILENAME" or <FILENAME>
Where section 1.2.3.4 in the c99 standard might explain the syntax of includes.
This isn't a particularly good example, but some of gcc's warning and error
messages are cryptic enough that a pointer to the actual language specification
could be very useful for some people.
Alternatively, or in combination, gcc could provide references to more
widely-available sources (such as K&R and H&S for C, and Stroustrup or the ARM
for C++ for example).
As another alternative, how about referencing gcc test cases to help the
developer understand the problem?
Thanks for reading.
James.
