Hi all,
I'm having trouble with getting correct section sizes under MinGW.
The example below demonstrates the issue:
(... abridgement ...)
Adding align(1) attribute to the data definition is a workaround, that fixes
the problem, but due to external factors I want to avoid adding it, if possible.
This behavior looks as a bug to me, but I can't say for sure.
Anyhow - is there some other (than the align(1) attribute) approach that this
behavior can be changed? Compiler option maybe?
`-malign-data=abi` shall fix the problem by minimizing the alignment
requirement:
```plaintext
E:\Desktop>gcc test.c -Wl,-s && objdump -h a.exe | grep -F test_sec
grep: warning: GREP_OPTIONS is deprecated; please use an alias or script
2 test_sec 00000040 00404000 00404000 00001c00 2**5
E:\Desktop>gcc test.c -Wl,-s -malign-data=abi && objdump -h a.exe | grep
-F test_sec
grep: warning: GREP_OPTIONS is deprecated; please use an alias or script
2 test_sec 00000024 00404000 00404000 00001c00 2**2
```
