Bug#1074850: [PATCH] Fix implicit int type errors in lex.c for GCC 14 compatibility

[Pablo Lucas Silva Santos]

Hi There,

I am submitting a patch to address the implicit int type errors in the 
`lex.c` file, which occur when compiling with GCC 14. The errors were 
due to missing type declarations for function parameters, which are no 
longer implicitly assumed in GCC 14 [1]

The patch includes the following changes:
- Added explicit type declarations for the parameter `c` in the 
functions `is_base64char`, `is_wordmidchar`, and `is_wordendchar`.

These changes ensure that the code is compatible with GCC 14 by adhering 
to the updated type requirements.

Please note that this patch has not yet been submitted to upstream. I 
resolved the issue by downloading the package from Debian unstable and 
applying the necessary changes.

As I am a new contributor to Debian, I am not adopting the package as a 
maintainer. However, I would greatly appreciate any assistance from a 
Debian Developer (DD) who might be interested in helping with this process.

Please find the patch attached. I would appreciate it if you could 
review and apply it at your earliest convenience.

[1], the implicit int type is no longer assumed, and explicit type declarations
are required.
